Summary

Model skis for radio-controlled cars. The skis themselves consist of 2 halves and are fastened with 3 m3x16 bolts.
The rack is attached to the ski with m3x30 bolt + m3 nut.
For the racks I made axle mounts through 12 or 14 mm hex. I printed the racks from TPU-a95 and the skis from PETG.
To prevent rotation, a corner or other element is attached to the top of the rack. So far I have only made a model for Arrma Gorgon.
