Printrbot 1403 (Metal Simple) metric M8 leadscrew nut mount
Description
(reuploaded because Thingiverse is a mess) The imperial threaded delrin block on my Printrbot was starting to have a lot of play, but with Printrbot defunct, it's impossible to get replacements. I didn't find existing designs that met all three of my requirements: * mounted at the bottom * similar shape and size as the original part * fit the particular nut I got with my leadscrew So I drew up this part based on some measurements with calipers and printed it up in ABS. Has been working fine during testing. This piece sits directly against the Y axis stepper motor, and the motors on the Printrbot run pretty hot, so wouldn't recommend printing this out of PLA, PETG or any other material with a heat deflection temperature at or below 70 degrees centigrade.
