I've designed an Ikea Skadis holder for the Radio Master Boxer Radio Controller. It has 10 hooks on the back which should give it a very secure fit. The front / sides are designed in a way that everything is visible, but it's still secure enough to keep the Radio inside the holder without a risk of falling out.

I've also created one for the ISDT Q6 Nano Charger

Niche designs like this one don't receive widespread attention, so I truly appreciate each and every boost. Your contribution not only helps sustain my efforts but also shows that there's a dedicated community interested in these specialized creations.
