DNA 250c with Modular battery sled
thingiverse
I'm designing a DNA 250c 3 battery mod, featuring an 18650 battery sled with an upcoming 21700 sled. The design was created using Fusion 360. Edit: I've added the 21700 sled model, but I haven't printed it yet. I've also uploaded a V2 of the 18650 sled with a cutout for using the JST connector if desired. I'm utilizing Keystone battery contacts (three of each): https://www.mouser.com/ProductDetail/534-209 and https://www.mouser.com/ProductDetail/534-228. For the case, I'll be using magnets from SupraMagnets: https://www.supramagnets.com/discs/202-disc-magnet-6mm-x-3mm-n35-0094922873316.html. The mod also features a 510 connector from Varitube: http://www.varitube.com/VT-510-V2-Connector--Self-adjusting-Center-Pin_p_364.html (I prefer the Stainless and Black smooth-top versions).
