(Yet another) Rear electronics case for Ender 3 Pro by TkrBox

Last crawled date: 3 years ago

Here's my (yet another) rear electronics case for Ender 3 pro.
It moves the mainboard to the hollow on the backside under the heating bed, freeing the front space. Also, if you're an Octoprint user, you can use the 'left case' to accommodate the Raspberry Pi board and DC converter.
This is a remix from Teaching Tech's "Ender 3 all in one, universal rear electronics case," which can be found here: https://www.thingiverse.com/thing:3688967
I want to properly attribute Teaching Tech as the origin of this remix, however, the web editor is not functioning well at this time. Hence, I've added the lines above. I recommend all viewers to visit, study and familiarize with the above original project before using my remix.
This edition is designed for stock mainboard & Raspberry Pi 4b. Will suit other boards with same physical dimensions, such as Bigtreetech's.
My design has:
Enclosed box structure with thicker walls and lids for sturdiness
Enlarged cable outlets for easier installation
Rail guides on sides and back, which are detachable to minimize the need for supports
Lids with mating slots on the back to ensure a better fit
Fan mounts and air inlets on both cases.
Printing :
8 copies of the rail guides are needed. Multiply them in your slicer. Also, rotate 90 deg so that round side faces down.
RPi ports cover is provided as an option. Print and use it when needed.
Fasteners etc:
Variety of M3 and M2.5 fasteners are used. When possible, I used threaded inserts to mate with the bolts.
Complete list of parts is in the attached PDF file.
Acknowledgement :
This project, like many other DIY projects, requires basic skills in electronic work. Please take all reasonable measures regarding electric safety. Power supply must be turned off and unplugged. Get familiarize with the electronic components and connector mechanisms before setting on to work.
Please take it slow and enjoy the process and the learning down the road. Happy tinkering!
