This model is designed to be printed in TPU as the tolerances are tight.
These v-mount batteries are great and available on amazon for a super low price! So I ended up with quiet a few of them.
Model: PS099E
The idea is to be able to pack these batteries into your bag with protection and the ability to turn on the display without removing the sleeve.
Ideal for travel on planes also (carry-on).
Print with slow TPU settings with or without support (snug)
