X-Axis Motor Mount, Strengthened

thingiverse

The standard equipment on the Tevo Tarantula falls short in several areas. I noticed that the stock x-axis motor mount flexed when I tightened the belt, prompting me to design a more substantial mount for that motor. Several versions of this type have been posted here on Thingiverse, but my design is sturdier and likely over-engineered like most of my creations. To install this new mount, you will need the following hardware: 8x m4 x 10mm screws (4 come with the standard mount) 8x m4 T-slot nuts (4 come with the standard mount) 4x m3 x 35mm screws 7x 4mm washers (one screw cannot accommodate a washer) 4x m3 washers 2x 5mm nylon spacers (one is used on the standard mount) Installation should be clear from the CAD drawing and follows the same steps as the standard mount, except for the front plate. All four m3 screws pass through both halves of the mount into the stepper motor. The idler pulley is sandwiched between the two halves with a 5mm nylon spacer on either side. The m4 screws go through the plates so that the t-slot nuts are on the inside, with washers between the screw and the plates. There are two "top" plates available. Version 1 is stronger but interferes with the mounting of the oldham coupler and z-axis drive rod, leading me to modify it to version 2. You may want to print the v2 top plate if you anticipate your rod getting in the way. I tested four designs before finalizing the top plate model, so look at the CAD drawing for accurate installation instructions rather than the photographs, which show an intermediary v2 plate that has not yet been replaced with the final version.
