Radiomaster Zorro 18650 Case/Holder - Nano Module Mount

This case holds a homemade 18650 battery pack and mounts to the nano module interface on the rear of the zorro. The pack can be easily removed for charging when needed and will easily power the radio for hours on end without using the internal cells.

The CG of the radio is unaffected so there is no misbalance, the cells are covered but are not glued into the radio and the xt30 connector is stored in a manner which allows easy access.

All parts were printed using a 0.32mm layer height however no design features require a given height. Supports are only required for the small tab that enables the module to lock into piece - I used tree supports and they were easily removed. I would recommend using arachne perimeters due to varying wall thicknesses.

Printed in PETG.

Battery:
I used several layers of electrical tape around my cells and it is a sliding fit - hopefully this allows you to tune the fit of your cells to your liking depending on how much you wish to remove it - I have included some images showing the profile of the cavity and the height for guidance.

I have also included a photo of my cell and the lenghts of the XT30 and Balance leads, the XT30 orientation is agnostic but I would try to match the lengths of my cables as close as possible - if anything make the balance lead slightly longer. 

Feel free to ask any questions and I can try to help. .sldprt are included so you can make any changes to suit your needs.
