Stacked acrylic case for the Open Frame 1 PCB (https://github.com/GregTurbo/Open-Frame1) using six 3mm-thick laser-cut layers. The button housings are from the OFOF1 (https://github.com/rana-sylvatica/OFOF1) by Bjart (https://twitter.com/rana_labs_), printed in LEDO 6060 resin from JLCPCB. I used the 3x panelized ones. The six layers are as follows: * 1 Top layer * 2 Support layer * 3 Above PCB layer * 4 PCB layer * 5 Below PCB layer * 6 Bottom layer These should accommodate any combination of OF1 parts you choose (internal usb c and cable, pin headers on the pico, etc.). You could also order a 6mm thick version of Layer 3 and use it for both layers 2 and 3. I use the 8mm holes in the OF1 to help hold the board in place with the bolts, and these .5mm compressible washers to help support it around the bolts. The hardware used can be found here. https://www.amazon.com/gp/product/B07QF6PS47/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 (15mm socket and 12mm screw version) https://www.amazon.com/gp/product/B07RBJZZDL/ref=ppx_yo_dt_b_asin_title_o04_s01?ie=UTF8&psc=1 (you could probably use anything similar just make sure it has an inner diameter of 8mm) I have three washers around each bolt on top of the board, but if you're using a different thickness and you need to raise up your OF1 board to get closer to the switches, you could also put them underneath the board around the bolt. Also - the bolts come in packs of 10 so you could edit the DXFs to delete a few and use only 10. It'd probably be just fine. I included DXF files but also SVGs as that's what I use when I go to laser cut at my local makerspace. Another note: the files are updated to provide more space between the edge bolts and the edge of the acrylic. The photos are of an older version - changed that after I put this together. This project is greatly inspired by Ryanemzed's builds (https://github.com/Ryanemzed/Self-Serve-Case) which I used for my first build, and got me thinking in stacked layers for case design. I also used the same bolts as he suggested in his build for this one. This design is not perfect. I ran into some issues with switches popping out of the housings. Figure this is due to the acrylic I bought not being exactly 3mm and messing with my measurements. I will likely not revisit it due to not being able to prototype quick enough and dial it in. I wanted to make an OF1 case out of exclusively stacked acrylic because I have access to a laser cutter, but only in 1 hour time slots every couple weeks. Since I can't cut metal or 3d print, I didn't want to worry about a printed case or switchplate. This design gets most of the way there. Ignore the single wire in the photo - had to bridge a connection due to a damaged pad. Shout out to Crane's Lab (https://www.craneslab.xyz/discord) for all the support and advice. Feel free to hit me up in there if you do anything with these files. Thanks for taking a look!
