Raspberry Pi 4B + 3.5" Touchscreen Case (For Printers with 4040 Extrusion)

Summary

This is a remix of existing design from Adam Vicknair from Grabcad

Original version was a side mount where the touch screen was facing towards the sides of the printer
It was inconvenient for usage with printers with 4040 extrusion on sides and no frontal extrusion to mount (most Ender 3 based printers)

Also made the USB cutbout a bit bigger to allow right angle connectors to fully insert into the port (dividers were an issue with broad body usb connectors as well as the holes didn't support as well)

The design was remixed to add 2 types of stand (Left mount and Right mount)

Mounting on Right side of printer = use "Pi Stand Right Side mount.stl"
Mounting on Left side of printer = use "Pi Stand Left Side mount.stl"

Other parts are common for both the side mounts

The Fan cover is an optional accessory which can be glued on to the stand
If gluing is not an option, you can grab the Merged option where the fan cover and stands are merged as 1 file so you can print as a single part and no gluing needed.

Raspberry pi case is a removable so you can dock it whenever you need to
Use 4 x M3 40mm Cap Head bolts and nut to secure the case

Cura 5.7.0 Universal Project File is also attached for easy print with cura
