Altera Wheel Chock for MTB

This is a wheel chock for the Altera tow mount bike carriers. It prevents the the handle bars turning when transporting modern long mountain bikes and replaces the universal wheel chock that is supplied with the carrier. Compatible with the Alter Strada DL, Altera Evo. The design accommodates up to 2.6" wide tyres. (tested on Maxis Minion)
There are two 3D models, I would recommend printing in PETG and separate the two models when printing:
1. Wheel chock. Requires remounting of the strap and buckle using a rivet (5mm x 15) Note: nut and bolt fasteners wont work due to clearance required on the strap.
2. A universal insert. Allows the use of other bikes with thinner tyres, like the original wheel chock.
