Trust Soundwave 20 loudspeakers mounts

I am still in love with my ancient Trust Soundwave 20 loudspeakers. They are standing on a metal bracket. This bracket can also be inserted in the top of the speakers so they can be hang. To maximize desk space, I decided to design mounts for exactly that.
I used Tinkercad for this mount: https://www.tinkercad.com/things/3yigCNPUhAH-loudspeaker-mount-for-trust-soundwave-20
