Double shear support for the rear idlers on Rook 2020mk2. Slim, quick to print, and decently good looking.
Use m3x30's through the support to mount the motor in the stock motor mount. Feet on the support fit into the countersinks for the bolts on stock mounts.
They are a bit tight to run the belts through, it helps to loop the belt around the motor pulley before installing this support, but it is not necessary.
There is plenty of room between the belts to get to the grub screw on the pulley for pulley height adjustments.
5/10/25 added a right side specific model with integrated spacer.
Left and right are mirrors of each other, the side with the relief goes in the back for belt clearance. Right side needs additional printed spacer for the single idler.
