Service holder for Trek IsoStrut from G1 Supercaliber/e-Caliber

Simple service block to assist with the service of the IsoStrut rear suspension from the Trek Supercaliber and e-Caliber bicycles.

Mount the block in a vise, and drop the IsoStrut into the block, lining up the forward mounting tabs into the slots. This holds the strut body securely so the air shock can be serviced. This holds the shock much more securely than clamping in soft jaws, as you would still have to clamp very hard on the shock body to keep it from rotating against the torque of the lock ring.

Please note!

This will likely not work on the 2nd generation Supercaliber with the RockShox SIDLuxe IsoStrut.

Printing instructions

Thanks to the wide flanges of the forward mounting tabs, this shouldn't need a terribly strong print. I used two shells and 20% infill at a 0.3mm layer height. Material can be pretty much whatever you want.
