FatShark Battery Holder for TATTU 2500mAh Battery

So, I purchased a replacement battery (TATTU 2500mAh)for my FatShark goggles. Problem is, it won't stay in the headband without slipping out. So, I designed a Case that slips over the the Tattu battery and now it stays put!

I printed it in TPU but I'm sure it would be fine (or maybe better) in PLA.

UPDATE: I made a Version 2 which has solid sides. The open side original version has weak sidewalls when printed in TPU, Ver 2 should fix that and make it stronger.

Enjoy!
