This is version 2 of the tennis racket wall mount, made of 2 parts so that the mounting mechanism is hidden and there are no visible screws.
It still holds 3 rackets but only uses 2 screws.
Note: I wanted to make a nicer design with no visible screws, but I have not printed or tried this one myself (yet). If you do, please leave a comment for any adjustments that may be needed. I've put the fusion360 file up if you want to modify it.
The author remixed this model.
