Universal e-bike conversion kit, with XT-90 connector junction box, and battery tray.

You might want to print this at 99% or 98% size as the xt-90 connector is a little loose at full size, or you could print the thin door. I have no intention of printing another full-size version at the moment.

This was designed to be universal, and hold (6) 18V batteries on top, as well as be durable enough for off- road use.

I made sleeves for frame diameters between 30mm-40mm, and 0,2.5,5,10, and 15 degrees. You can make sleeves for other sizes and angles.

I printed this with a 1mm nozzle and PETG.

I have printed this at 78% size, for smaller 36v-48v controllers, and used XT-60 connectors in the junction box. You will have to make a sleeve. I was able to fit a 48-72v motor controller, after removing the end plates from the controller. The XT-60 connector fit is pretty tight at 77% size. 78% size seems just right, keep in mind I'm using a 1mm nozzle, your results may vary.

NOTES:

• UMCH, universal motor controller housing.
• Large size is to hold 72V motor controller, or possibly (2) controllers.
• EZPRINT version should be printable without supports, but will require bridging. (60+ mm bridging.)
• Some of the 15 degree angle sleeves may not fit without modification.
• I used 3" screws for holding together main housing.
• I have uploaded a 78% version. E-bike conversion kit V2 (universal)
• I may add a battery cover or other parts in the future.
• I will upload more pictures soon. Lightning V2 pictured.
• I have added a thin version of the J-box door, I've taken a little off the inside to get a tighter hold on the xt-90 connector.

Happy printing!!
