CR-10S5 Y belt tensioner Mk2

thingiverse

Belt tensioner for cr10s5. Edit on my first design. No longer uses part of the original bracket. This will also fit on any 20x20 profile but check the height of the belt over the profile. A bit more sturdy and easily printable design than the other tensioners i found for the cr10. Also added is an experimental bracket that maybe fits smaller models CR10 that have a 20x40 center extrusion. I do not have that printer and can not check if this is at all suitable for that model printer, added it for anyone interested and willing to experiment. No supports needed. Reuse the roller, but need new m4/m5 screws and Tnuts. This version is made for the more easily avalible m6 bolts for adjusting rather than m5 that other versions have. For a knob i simply scaled up 120% the knob from other designs. I printed the main bracket standing vertical and the rider sitting flat. No changes to the rider so if you have the first model you can reuse it. I have yet to actually print this as my machine is busy for a while, but it should fit as it uses the 20x20 extrusion. - Post note - I recently found out that it is easy to remove the bed with carrier on my cr10s5 with this mod. Simply unplug the cable, unscrew the adjuster knob and bring the rider out of its track and pop the enc covers on the 2040 extrusions and the whole assembly simply slides off for easy maintenance. The bed carrier should go clear of the tensioner.
