Treefrog bikerack adapter for universal wheels

Treefrog solution for bikeracks on vehicles is awesome. Very sturdy and rigid. The system that allows multiple adapters for each different type of wheels and bikes is great, but owning a 3D printer will allow you to save a few bucks without compromising the solidity of the rack.Here is an adapter, built on ASA (best for outdoor use), for a universal classic front wheel axis bike.
