Description
Here is a simple and effective Z axis belt tensioner for the Anycubic Kobra 2.
.
.
Designed to fit in with the original aesthetic of the Kobra 2. These mount directly to the metal bracket that the Z axis lead screw bearings sit in. These tensioners keep the bearing correctly seated and utilise the two M3 holes either side, to fasten the tensioner in place.
.
.
You will need;
TWO 608 bearings - standard skateboard bearings (8X22X7mm)
SIX M3 x 10mm bolts (Stainless dome heads are recommended for aesthetics)
.
You will need to print one left, one right and TWO bearing caps. Simply assemble as shown in the pictures and bolt in place.
I would recommend printing at 100% infill simply to add rigidity.

If you print these and are happy with the design, please consider uploading a photo as I would love to see them.
