X-Axis Motor Mount, Strengthened

cults3d

The standard equipment on the Tevo Tarantula falls woefully short of expectations. Upon inspecting the stock x-axis motor mount, I noticed it flexed alarmingly when tension was applied to the belt, prompting me to design a sturdier replacement. Having seen several versions of this modification on Thingiverse, my own creation boasts greater solidity and, likely, an excessive degree of over-engineering, as is often the case with my designs. To install this upgrade, you will need the following hardware: 8x m4 x 10mm screws (4 of which are already included with the standard mount) 8x m4 T-slot nuts (4 of which are also part of the standard equipment) 4x m3 x 35mm screws 7x 4mm washers (a washer cannot be fitted to one of the eight m4 screws) 4x m3 washers 2x 5mm nylon spacers (one is used on the standard mount) Installation should be self-evident from the CAD drawing, with the exception of the front plate. The four m3 screws pass through both halves of the mount into the stepper motor. The idler pulley is positioned between the two halves of the mount, supported by 5mm nylon spacers on either side. The m4 screws traverse the plates so that the t-slot nuts are housed within, with washers situated between the screw and the plates. There exist two distinct "top" plates in this design. Version 1 is the most robust but interfered with the oldham coupler and z-axis drive rod mounting, prompting a modification to version 2. You may want to print the v2 top plate if you anticipate any issues with your rod's clearance. I refined four different designs before finalizing the top plate model, hence the discrepancy between the actual photographs and the CAD drawing.
