This Slip Case is somewhat of a remix, and I'm not sure who should get credit for the original design, but it has been redrawn and heavily modified. I added much-needed venting and changed the design to accommodate a Waveshare 3.5" RPi LCD (B) display. This case should fit all Raspberry Pi 2 and 3 versions.
The 3.5" tft touchscreen display used here can be purchased on Amazon, https://smile.amazon.com/gp/product/B01N48NOXI/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1, and I'm sure other places as well.
Here is a link to the manufactures website for the display used. https://www.waveshare.com/wiki/3.5inch_RPi_LCD_(B). * You have to copy and paste this link bescaue it will not include the close paren and link will fail.
I also wanted a stand that had an adjustable viewing angle. The rotating uprights are able to be adjusted to several detented positions. The included stand was designed from scratch by me.
No fastening hardware required. Everything snaps or press-fits together. Assembly should be self-explanatory by viewing the pictures.
You will have to print 2 of the stand's Uprights.
This case was printed using ESun PLA+ and it's very durable and strong. I haven't tried using ABS but, I think it would be fine to use as well. I don't think I would recommend using standard PLA. I think it might be too brittle for the snaps.
This was printed on a Lulzbot TAZ 6 using the standard 0.5mm nozzle.
