X-Axis Motor Mount, Strengthened

myminifactory

The standard equipment on the Tevo Tarantula falls short in many areas. I noticed that the stock x-axis motor mount would flex when I tightened the belt, so I chose to create a more substantial mount for that motor. I've seen several versions of this type of mount here on Thingiverse, but my design is more robust and, likely, over-engineered like most of my creations. To install this upgrade, you will need the following hardware: 8x m4 x 10mm screws (4 of which come with the standard mount) 8x m4 T-slot nuts (4 of which 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 of which is used on the standard mount) Installation should be clear from the CAD drawing and resembles the standard mount, except for the front plate. The four m3 screws pass through both halves of the mount into the stepper motor. The idler pulley is sandwiched between the two halves of the mount with a 5mm nylon spacer on either side of the pulley. 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 the strongest, but it interfered with the oldham coupler and z-axis drive rod mounting, so I modified that to version 2. You may want to print the v2 top plate if you anticipate your rod will obstruct its path :). I worked through four designs when modeling the top plate, so in the photographs of this installed, the (intermediary) v2 plate has not been replaced with the (final) v2 - I simply removed the two outer mounting screws, so... refer to the CAD drawing and not the actual images. In the photo uploaded of my test tower, you can see the significant improvements with each modification made. From left to right, the first tower is prior to my latest upgrades. The second tower is after installing the no-sanding oldham coupler (not my design). The third tower is after installing this upgraded motor mount.
