Cover for Openbuilds Nema23 Reduction Plate

thingiverse

I designed a cover plate to fit the top reduction pulleys & belt on my Sphinx 55, adding a splash of color and personal touch to my machine. You can choose from various logos - Sphinx, OpenBuilds, or keep it plain - making this a versatile accessory for any DIY enthusiast. I secured it using M5x10mm screws that fit perfectly into the four threaded holes on the top reduction plate. I also created a test print to help with mounting the Z-axis limit switch cover, which will be uploaded separately. This test print comes in handy when adjusting the pulleys manually to achieve an optimal limit switch distance. To get started, print the test file **Z_ReductionPlateCover_TestPrint_Rev17.stl** first, ensuring it aligns perfectly with your plate and allows for easy manual adjustments later on. Then, print any of the files prefixed with **Z_ReductionPlateCover_**, as the other STL files are solely for reference in the OpenSCAD source file provided. I used eSun light blue PLA+ to bring this design to life, opting for 20% infill and three perimeters, while varying the layer height between 0.3mm and 0.2mm. The printing process took approximately three hours, using 10mm length screws as the maximum recommended. Feel free to experiment with M5x8mm screws if needed. This cover plate is designed for compatibility with the OpenBuilds Mini-Mill and other machines that utilize the reduction plate & C-Beam double wide gantry plate combination.
