Heusinkveld handbrake controller cover

Hi im new to 3d printing and i do sim racing so just messing about with things to learn fusion 360.

Just a quick design for my heusinkveld handbrake controller box.
theres a hole inside for a m5 bolt so it can be fixed to your sim lab or trakracer rig.
if you have nowhere to bolt it too just use some doubled sided tape.
