3D Printer Electronics Test Bench

I wanted to be able to test the electronics and firmware for my 3D printers without having to take a machine out of service, so I designed a modular test bench for the purpose.

It is designed to use a 24v 10a+ power supply, and has step-down converters to get 12v and 5v for powering lights, Raspberry Pi's, 12v boards, etc. All circuits are fuse-protected.

The parts are labelled to aid in assembly and component placement during construction, and then the various mounting plates are labelled with the component they are designed to mount. Blank STEP files are also included in order to allow additional mounting plates to be made.

Print all parts using PETg or another suitable self-extinguishing material. There are 6 feet for the legs to be printed from TPU.

This print will require a bed at LEAST 250mm x 200mm.

Parts List:

8x M3x10mm Socket Head Screws for mounting electrical components to the board bottom
8x M3x16mm Socket Head screws for mounting main board and motor b
