Smartrapcore Alu - Strengthened and anti resonance Upgraded Parts

thingiverse

These are remixes of parts for the SmartRapCore Alu by Smartfriendz. Please see my other things for some other parts I've reworked - I might add them all to one listing at some point. Update: See here for an improved version of the rear pulley holders: https://www.thingiverse.com/thing:1655402 X and Y (L and R) motor mounts L and R Bearing holders (also the rear y-axis smooth rod holders). The R side xy smooth rod support with proper locating lug, plus the motor mounts, feature an extra spar for strength. This has helped reduce resonance in the frame, especially with stock motors that are rather prone to vibration. I remixed the original pulley/bearing holders because they broke after a few attempts to adjust the belt tension along the layers (photos below). So I added more "meat" around the m8 holes for the pulleys and thickened the lower aspect. It would be nice to print these with the layers 90 degrees rotated in the x dimension, but that would require awkward support. Update - I've remixed the R motor support/y-smooth rod holder. This part wasn't ideal before because it had no locating lug to position it in the frame. So I basically mirrored the L side part and added screw holes for the motor and the endstop holder. The motor might need a couple of washers between it and the motor bracket. Printer Settings: Printer: Kossel Mini/SmartRapCore Alu Rafts: No Supports: No Resolution: 0.2-0.4mm Infill: 40% Notes: Just print 'em nice and strong - I've been replacing stock PLA parts with ABS because it's stronger, more flexible, and if you ever want to enclose and heat your printer, you'll wish you had done this in the first place.
