Quick release X-belt tensioner for Prusa i3

thingiverse

The original belt tensioner design often needs a critical update, incorporating a quick-release option to maximize the lifespan of both the belt and its related x-carrier bearings. The addition of a toothed idler can be accommodated on standard 10x5 idler bearings, with this component serving as an optional upgrade. Below you will find the step-by-step instructions to create this essential part: First, prepare your print settings by selecting 'print upside down' for the excenter lever and include a 'brim' feature to enhance its adherence to the printing bed. It's also highly recommended that support structures be added during the 3D printing process. To secure your printed parts together with high-quality adhesives: • Install two M4 x 40 bolts, working individually or as part of a bolt assembly. • Secure a single M5 x 25 bolt with its respective nut (also classified under type M5), making sure it is positioned firmly.
