All the parts were designed with FDM 3D-Printing in mind, without requiring any printing support. The case has a snap-fitting lid design that snaps into place without the need for any screws or adhesive. The case currently supports one type of battery, other batteries may fit if they are under the dimensions of 8mm x 40mm x 40mm.
(Support for different IMUs and extensions is in the works)
Make sure to check GitHub for different IMU Support.
