Made in Fusion to hold my IEM recievers, but also fits any other Sennheiser transmitter or recievers with the same form factor. It uses Gridfinity and is 2X5

I left a little bit of play to account for the clips sometimes bending out. But it's relatively snug. I'd like to try adding in some kind of strap from front to back to secure them in transport a little better though.

This could be easily adapted to different brands of wireless as well. It fits my Lectrosonics SMDWB's with the spring clip as well as my Lectrosonics LR/LT. The holes would just need to be thinned slightly for a snugger fit.
