Prusa Y Belt tensioner for SAE Hardware and T-5 belt

Creation's quality: 0.0/5 (0 votes)
Evaluation of members on the printability, utility, level of detail, etc.

3D model description

Same design as chrille but modifies to use 6-32 nuts and bolts.

Update: Added belt attachment with teeth for the other end of the y-belt.

3D printing settings

Non-tension end(back of y-carriage):
1. Place the part with teeth cutouts facing up and line up with the holes on the y-carriage.
2. Lay the belt teeth into the teeth cutouts.
3. Install the retainer cap with the notch facing down.
4. Install the 6-32 washers and bolts and tighten, this does not have to be super tight since the teeth are doing the work, not the clamping force.

Tensioner end(front of y-cariage):
1. Insert captive 6-32 nut
2. Bolt the two parts to the plate, so the bottom part has the belt slot facing down towards the plate and the captive nut is facing towards the middle of the plate. The top piece should have the teeth facing down, grabbing the teeth of the belt.
3. Screw in the 6-32 tension bolt (I used a 1" bolt)
4. Adjust the bolt till you get the tension just right
