Ultimaker Short Belt Tensioner

thingiverse

Introducing the snap-on floating belt tensioner, ideal for frequent tightening of short belts! The tensioner's roller parts feature flanges that prevent it from falling off. For noise reduction, attach felt to touching surfaces. Print the required parts at 0.1mm layer height with 1.2mm wall thickness and 20% infill. Ensure smooth movement by cleaning bores and tightening roller screws loosely. Check for smooth-running rollers and sliders before attaching tensioners to belts. Snap the belt tighteners onto short belts, ensuring flanges embrace the belts. Adjust pulleys for 1-2mm clearance from walls. Rollers should barely touch without scratching. The bill of materials includes two slider parts, roller parts, ball bearings, and screws. Save nuts and glue guide bar screws into one slider part. Recent changes were made to the roller part for improved performance.
