This is a very quick n dirty version of a 30mm Batterie Holder for the Traxxas Slash 4x4. (Had to be ready to race over night including printing...)
Fits into the Standard Batterie Holder Holes/Pins but replaces the Bridge to host Batteries with 30mm hight. (3s 5000mAh)
Turned out to be light, flexible and durable, quite happy with the result, already survived a very hard bashing day.
Happy to see some more refined/curved designs as your remixes.
3d ware PLA
5 Top and Bottom Layers, 4 Perimeter-Walls, printed with 0.4mm Nozzle
Print upside down to minimize support.
