Something is stirring in the east
Clouds grow thick over Mordor
The forges of Barad-dûr have been re-lit
Sauron has returned
Hello everyone
After a long pause, I’m back.
I got sidetracked by real-life, and the project was on hold for a while. Nevertheless, I always intended to finish it, and late last year I decided that IT WILL be finished by Halloween 2024, and made a strong mental commitment.
That was a fair amount of time, and clearly doable. However, I knew I would need to get some work in on as many days as possible, to keep up the momentum, but also, to get some prints out. This project with all the printing is not something you can just cram out by working really intensely for a short amount of time, even weeks of crunch. And it’s not just the final print itself, it requires a lot of prototype prints, and general problem solving.
So, a thing I did was to create a physical calendar on my makeshift white board. In part It’s a physical reminder of the project, so it’s always on my mind, and you are more likely to work on it.
It’s very simple, there is a box for each day from then until Halloween. Each day, I either worked on the project or not, red x if I did not, and a green check if I did. This is surprisingly compelling, you don't want that red x.
Other people might be motivated by telling friends about the project as a way of making themselves accountable, and therefore feel obligated to work on the project, since they otherwise would fail. This does not work for me, if anything, telling someone about the project makes me feel that I cash in on the glory early, and I lose motivation.
Many people know that I’m working on an ambitious Halloween costume, but no more than that. Which, Ironically, actually does help me feel accountable and makes me motivated. Cant wait to show people what I’ve been making.
Anyway, I figured if I can just bring myself to work on the project for a few minutes every day, that will often lead to those few minutes becoming more, getting started is the hardest part.
And this method has proven surprisingly effective. Another part I did not count on, is the importance of streaks. Where once you are on a streak, If I worked on the project even a little the previous day, then I'm way more likely to do it the next. Also works the opposite, if you can easily have a hard time getting on again if you have a break.
Anyway, I have gotten a lot done since December. Basically have a prototype for most of the parts besides the legs. And have now started printing some final versions.
So for this project, every part has essentially 4 main stage.
- Base model
- Prototype
- Final print
- Finalization
Basic model
The first stage is just building the base model off of all the references you can find. It’s not going to be 100% accurate, there will be adjustments in the prototype stage anyway so it does not have to be perfect, you just need to get the base shape fairly accurate, not the details. I have done this stage for all parts even prior to the hiatus.
Prototype
Base models are usually just the outside of the model. With the prototype, you have to give and inside / thickness. Then figure out how best print it, consider mobility, so you can move enough, and lastly, but most importantly, you have to make sure it fits your body.
This is is not entirely simple, as there is a fairly narrow window you want to hit. You of course don't want it to be too small, as then it will be uncomfortable or impossible to wear, and move around in. But you also don't want it to be too big since then things just float around, you want a tight fit. So you want to get it down to less than half an inch of space. Depending on what you are wearing underneath.
So you need a good reference in the digital world of yourself prior to printing, more on this later. You can of course brute force it and just print, adjust, print, adjust, until you get it right, but that is both time consuming, and costly.
So, since Christmas I have prototyped about two thirds of the costume, and most of them have turned out surprisingly well on the first go, some have gotten many many versions.
I would say though, even if you think you could nail it on the first go, a prototype is always worth it, there are always a lot of things you immediately stand out to be fix once you have it in your hands.
It’s also very motivating to hold the thing in your hands. So if you have a project with 3d printed parts, and you feel you can spare the filament, don't hold off on printing a prototype, as I will gain you so much. I realized that the hesitation to do prototype held me back, the desire to make final prints on the first go makes things go a lot slower. So then I just let it rip.
Final prints
After the prototype is done, there is still a lot of work left before printing the final model. In this case, almost every part has textured details, which means there is a point of no return, where after details have been added, if you want to change the base shape, there is a lot of work that has to be redone. So therefore I only do this once I’m happy with the prototype. Several pieces have finished this stage, as such I can now start printing many of the parts.
Finalization
Last stage is of course some sanding, covering it with spray filler, sanding again, painting etc. I’ve lightly sanded the few pieces that have gotten to this stage, but no more than that. I will likely focus on getting all the models to final print first, and then focus on finish after this. I think the 3d modeling is the hardest part. The last parts, sanding, painting etc can actually be done in short time if needed, the 3d part is the hard part to get through.
I’ve printed the final version of the mace, as that one was completely finished from before. I just needed to decide what material and settings to print it in, which I’ve decided one what material to print it in. (More on that in a future post)
So earlier this week I printed the final version of the breastplate and assembled it. Some light sanding, brings out the pattern real nice. Really happy with it, and look forward to the relentless printing that will be going on for the next few weeks, so there will be a lot of updates in the near future.
I realize seeing this picture, that it looks like there is very prominent print lines. This is actually very inaccurate, the model comes other fairly smooth as is. And with just a light bit of sanding, its very smooth. It just the sanding makes it look like it's got very heavy print lines. Basically, the white lines are the areas that are sanded down. So worry not, it's turning out great, and with some thin layers of spray-filler it will be perfect.
A short recap of why the big pause, and what happened in between
Some of this is relevant I promise, or perhaps amusing.
So in the spring of 2021 I was on a roll, got the helmet and mace done and printed. Then several things conspired to halt my project. I had a lot of issues that conspired to halt the project.
My printer broke down, and getting the parts, and finding the motivation to repair it took time.
The biggest thing though, was, 8 metric tons of concrete blocks and slate arrived on my driveway so this needed to be dealt with. This was for my garden, så I had a fair amount of work getting them into place.
Preparing and figuring out the place they needed to go, puzzling and cutting up the slate etc. Just the work of moving each piece was a lot of work. So most spare time during the summer just went to working with stone. After the summer I was pretty spent.
Simultaneously something that had been on my mind for a while, was the wish to have a bigger printer. That would for instance make it so that I could print the helmet in basically 2 parts instead of 4, and the breastplate in 4 pieces instead of 12.
I knew that there were a few available I could at any time could print 30, 40 or even 50 cubic centimeters. But I wanted it to be a very reliable printer, since these prints take days, and you don't want a failed print after days of printing. Just the thought of the cost for the lost filament was fairly unpalatable, never mind the lost time. In short, what I wanted was a larger Prusa.
And wouldn’t you believe it, just then, in the autumn of 2021, Prusa announced just that, an XL printer was in development. I pre-order as soon as I saw it. Not cheap, but the 3d printer I have, has been one of the most rewarding purchases I have ever made, so there was almost no hesitation.
Now, the set delivery date was Q2-Q3 2022, and even under normal circumstances, I had no illusions that Prusa would deliver on that, the RnD and time to set up production, plus pandemic slowdowns, it would take more than that. I expected a delivery no earlier than Q4 2022, but likely later. Which turned out to be true, The delivery would take place late Q2, 2023. So waiting for this slowed me down a bit.
So, in the meantime there was not a lot going on with the project. I never forgot it, but progress was almost non-existent. But not completely. I did some tests in photo scanning myself. As mentioned previously having a good reference for your actual size is pretty crucial. As the margin of error is not that big, if you want to wear it and walk around in it comfortably.
Photo scanning myself proved very difficult though, so the results were pretty disappointing. Its just really hard to stand still enough and take all the pictures, and have them be sharp etc. But they still helped.
Anyway, time passed by late summer of 2023 the printer finally arrived, and this is when the project started to pick up again. One of the main things I did was to create a papé-maché bust around a sewing manikin I have. It’s not exactly the same shape as me, but at least I could photo scan that properly and have a decent reference for real-world size in the computer while modeling. I could also actually put this paper armor on, to see where the differences were, and therefore be pretty confident that It would fit. So with that I could do the Breastplate and Gorget with a fair amount of confidence.
Btw, don’t dismiss papier-mâché, its dirt cheap, it’s a great tool for some things. That being said, if anyone has a tip for how to make fast models that would be great. As papier-mâché takes forever to dry. I’ve used worbla in some cases, but it has the downside of being more expensive, and needs to be pretty hot to shape, so you cant easily do it on your body.
After halloween 2023 is when things really picked up though, I got my white board, and I was working on the project on at least a weekly basis, with only 2 major disruptions where I went traveling for 3 weeks on 2 occasions, and some time adjacent to that.
So the project has been ongoing pretty well. 7 months down, 5 months to go. So as mentioned I have prototypes for more than half of the armor at this point. And for the next few weeks I will be printing non stop for a while, as many of these piece take 3-4 days to print. Current print is 112 hours. Here is a bit of a teaser for the next part.
