Raspberry Pi 4 and Arducam case with ball joint and 2020 rail for OctoPi

thingiverse

This is a tool-less snap case for a Raspberry Pi 4b and Arducam OV5647 (https://www.amazon.com/gp/product/B013JTY8WY/?tag=tvad0304-20&th=1). I wanted an OctoPrint setup for my Creality Ender 5 Plus, but none of the cases I found here on Thingiverse had case for both the Pi and the camera, or any good way to mount them. I liked the snap fit of Malolo's design, and tweaked a top and bottom of the Pi case (sorry they don't match, I couldn't get the Slot stl file to convert for editing), then copied the dimensions of the snap lips for my own version of the camera case. The 2020 Aluminum extrusion that makes the frame of my Ender 5 Plus is very common on Creality's other printers, so this case will probably work for many of their other printers. You will of course need to break down the frame of your printer a little so that the ends of the 2020 are accessible and the case can slide in. This is not intended to be easily removable, and the case locks together very tightly, so be sure you have any heat-sinks or other accessories installed before closing the case. The lens cutout is large enough to fit the basic lens through (without lens cap). Added an extra linkage for more flexible camera placement. 02-28-2021 Update: Found that the bottom case rail I added didn't work with the 2020 rail on my printer (I was using a different rail for sizing and testing). Updated the model with corrected values. Warning: I'm finding my printer isn't as dialed in as I hoped, so the models work for what I currently have for settings in Cura. I'll probably work on the tuning and update again later on. 03-30-2021 Update: Finally was able to test the new bottom case rail, and it works with Creality 2020 rails. It's fairly free to move, so if putting it into a vertical rail, you will need to support it at the level you want it to be, such as with tape or a t-nut. Also, the ball on the top case has worn down a little over time, and is now pretty loose. I'm planning to paint a few coats of super glue onto it to build up a little more thickness.
