Frsky - FASST TM-8 module holder

I have a Futaba FASST TM-8 HF module which I use with a Flytron adaptor in a Frsky Horus. So far so good. The module is connected but very flimsily.
I couldn't find any mention of a solution for that problem neither here or elsewhere. So I took the bracket as a basis and made some changes. It holds quite strong, but is difficult to loosen.
The problem is that the module has only very thin space to the left (picture) and nearly none vertically. Most of the designs are made for smaller modules
