Ender 3 Pro Versatile Case

thingiverse

This is an electronics case for Ender 3 Pro designed specifically to support any internals. The base has a hole mesh pattern so that boards and cables can be attached using 2.5mm zip ties. The cases are symmetrical and are slightly smaller than the frame to prevent situations where they don't fit after you've spent hours printing them (talking from experience with other models I found in the past). They can be bound together using M3 screws, but that's not necessary. They come with lids with holes to let the Z-axis cable through (on both sides, if you have a dual setup). The back of each case has holes for ventilation and for cable. However, there are no holes for ports for components like Raspberry Pi for instance. Instead, you can connect the components internally. This is useful if you're not interested in getting access to the USB or Ethernet ports and just want to connect the Pi to your motherboard. It ends up being cleaner since you don't have extra USB cables dangling at the end of your printer. The cases are supported on the left and right by sliding them in the beams' grooves. There is also a lip at the end of the case that slots in the central beam for more rigidity. I've printed mine with black PLA at 2.2 layer height, 210 deg, bed 60 deg. I've provided Gcode files for the Ender 3 Pro. The cases only need support for the lip at the back, the left and right overhangs are designed to print without support. In practice, I had to set the overhang in Cura at 70 deg to exclude support for those but they were designed with a max 50 deg slope. However, the lids do require support. STEP files included.
