Bicycle body holder for wall holder

I made a wood holder for my bicycle, and I needed a piece of plastic to make it stable on the wall, so I designed this simple holder and attached it on the wood holder.

Model dimensions
20mm*70mm*30mm with thickness of 8mm

I printed it with PLA in 1 hour and 15 minutes, but I believe a PETG or ABS is a better option, especially if you have a mountain bicycle.
