Raspberry Pi Vertical Case Optimized for shorter printing time, fewer fasteners

thingiverse

This is a further iteration of my Raspberry Pi Mini Desktop Vertical Case with 40mm Fan Original here https://www.thingiverse.com/thing:3921288 Currently this version fits the Pi 4 only. Pi3 version may be added if requested. This version is fully compatible with the previous version in almost every way, but differs in a few ways that make it a shorter print, and use fewer screws and nuts, but sacrifices some of the vault-like strength of the original design. The big change is that one of the support structures in eliminated, eliminating 8 screws and 8 nuts in the process. Also this reduces total print time by about 90 minutes (Ender 3 default Cura print settings) Furthermore, the all of the outer faces are thinned from 1mm to .8mm in thickness, reducing it from 5 layers to 4 layers at .2mm layer height. In total this reduced print time by about an hour total. Additionally, the structural part that remains has had a redundant cross brace removed and three of the sides are narrowed 2-3mm. This was done more to open up the design for visual purposes when using clear acrylic sides, but it has the side benefit of reducing print time by a few more minutes. And finally, the screws that hold the lid on now screw into plastic bosses on the sides, rather than screwing into captive nuts, reducing fastener count by 4 more. The down side is that it is not as strong as the previous version. Particularly the sides can be spread apart on the forward facing side near the bottom. Thus the sides and the bottom cover end up with a slightly wider panel gap than the original version. A big plus to losing the secondary support structure inside is that when using clear acrylic side panels, the entire top of the Pi is visible - if you're into that sort of thing. Otherwise, everything said about the previous version in the listing, in the linked Imgur galleries, and in the YouTube video linked from the previous listing are still valid. The strain relief and blanking plate featured on the other version still work, but as nothing changed I did not reupload those parts. They can be taken from the other listing and used if you like. There's a youtube video my normal meandering style showing this case and the changes made. https://youtu.be/URz4usRlADI --- Also, in the old version there is a part called FACEshimADJUSTED that is a shim 1mm thick to fit in the same slot as whatever material you use for the face (wood, acrylic, etc). You can scale it in Z axis for whatever thickness you need to make up. It also works well as a guide for marking your material for cutting. The blue acrylic faces I have used are 3mm thick and 6mm thick. The 3mm thick acrylic could use a 3mm thick shim, so scale it up 300% in Z axis. The 6mm thick is a good fit on its own. I cut the acrylic with a jigsaw with a metal cutting blade (24 teeth per inch) and it cuts easily, leaves a fairly smooth cut, and is easy to follow a straight line. The rails that the face slots into are 6mm deep, and I suggest you err on the side of too small by 1mm-2mm rather than too big (cut inside the line instead of outside the line, if you use FACEshimADJUSTED as your guide. Below is a link to the two acrylic panels I bought for this project. https://www.amazon.com/gp/product/B006FLYG1W/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1 https://www.amazon.com/gp/product/B07KMYN5V9/ref=ppx_yo_dt_b_asin_title_o06_s01?ie=UTF8&psc=1
