Gnarly Primo frame self-adjusting Battery Holder

thingiverse

A self-adjusting battery mount/holder for Gnarly FPV Primo frame. I have various brands and sizes of 2S Lipo batteries. The stock battery holders came with Primo kit don't fit some of my batteries. So I created this mount that has a self-adjusting feature to fit all my batteries, such as RDQ 2S 450, RDQ 2S 300mah, Tattu 2S 450, Betafpv 2S 350, etc. Printed it using 20-30% infill 0.24mm layer height TPU. 5/12/2019 - Added version 2. 5/19/2019 - Removed version 2 and replaced with Version 3. (Version 2's hole was slightly off and not centered correctly). 5/19/2019 - Added Versions 4 and 5 per request for larger batteries. Changed the design slightly to accommodate slightly bigger batteries. Version 4 is very stretchy, but a bit too stretchy for my other smaller batteries. Version 5 seems to be a good balance - stretchy enough but not too loose. You may need to play with infill settings to best fit your larger batteries. I used 0.24mm layer height 50% infill for version 5. Version 3 works best for Tattu 2S 450mah and RDQ 2S 450mah. I used 0.24mm layer height and 30% infill. If you are not sure which version to use, start with version 3.
