Wheel presentation, stand and hangers

Hello, I've made models to better display or store our steering wheels. The QR adapter can be screwed directly onto a surface or attached to the stand with 3 or 6 M3 screws. The hook fits perfectly on Ikea hanging shelves or other shelves with a 5cm thickness, but it needs to be sliced down a bit further, approximately by 110%, otherwise the steering wheels will fit very tightly in the hook. The QR adapter has a circumferential groove, so the steering wheels lock into place but can still rotate freely with some resistance.
