X axis belt tensioner with GT2 idler for Creality Cr-10 and Ender 3
Description
T: X axis belt tensioner with GT2 idler with 5mm bore (toothed or smooth) for Creality Cr-10 and Ender 3 This is my version of belt tensioner. Others that I found on thingiverse are either not working due to part being too weak or tolerances are very tight and parts does not fit together. This design is bulky and tolerances make printing with ABS, ASA, PETG available. It should work with Cr10, Ender 3 and other printers with gt2 belt with v-wheels on 2020 profile at X axis. Parts needed : - 1pcs M5x30 hex head screw - 1pcs M5x25 screw - 1pcs M5 nylock nut - 1pcs M5 nut Mind the order of the assembly ( to avoid frustration ;) ) : 1. Insert M5x30 hex head nut into the idler holder ( p2 ) 2. Make belt go thru both holes of main part ( p1 ) creating u turn between in and out. 3. Take GT2 idler and wrap belt around it 4. Insert belt into idler holder (p2) but do not add M5x25 screw before inserting it into the main part (p1) 5. Add back plate (p3) and screw knob 6. Place main part with idler holder and tighten the belt to make it fasten itself 7. (...) 8. Profit The knob used is not my creation and can be downloaded from here : https://www.thingiverse.com/download:3537783 It is from this design : https://www.thingiverse.com/thing:2233139 I just had it laying around so i did not designed new one.
