Direct Drive Extruder Tension Lever
thingiverse
To improve my direct drive extruder, I altered the design since my stepper differs from others. Removing the bearing mount relief was necessary. Inspired by Thingiverse's "QU-BD Extruder Modifications bdring," I used 624HZZ A5 bearings mounted with 10x4mm pan head screws, secured with superglue. A small Hillman 4mm flat washer is included. Clean the pivot mounting hole for a snug 6x32 bolt fit while allowing free rotation (#28 drill). Note that for NEMA 17 stepper direct mounting, use an appropriate M3-.50 screw (I use 10x32 as I don't attach the bearing tension lever to the motor; instead, it's mounted on my adaptor for a gearhead motor). Clean the bolt holes guiding pressure springs (#37 drill) and tap with 6x32 tap. Install two 6x32 hex head bolts for spring guidance and holding. Note a previous instruction error: use 10x32 bolts, not 6x32, as stated earlier.
