Arduino T-Slot Extrusion mount

thingiverse

Here is a quick-access bracket designed to provide easy access from outside to the USB and Power connectors of an Arduino/RAMPS in a T-slot extrusion machine design. The bracket designs for 2020 (20mm), 1515 (15mm) and 8020 (1") are available for download, with the OpenSCAD source also included for those who want to fully customize this. The PCB mount holes are designed to be self-threading for M3 screws (M3 6mm should suffice but wood/plastic screws work here too). The screws that mount into the extrusion are M3 for both 2020 and 1515, and 1/4" for 8020 (but can be fully customized - for example, using M4 or M5 on 2020). How I Designed This I needed a bracket for my 2020-based delta but found that most brackets on Thingiverse ignored the USB connector or placed the board in an odd orientation or were simply too complex for the job. It's designed in OpenSCAD and is parametric, with 1.2mm walls seeming to work well but 2.4mm working better. There are two ways to mount it: either inline with the extrusion or on top of it. The aligned holes allow for easy access to the screws without needing to remove the Arduino board.
