Campus Rider: DIY modular electric long board MK I.5
Current MK I.5 Board:

Hey everyone, I've been itching to build an electric skateboard for a while since I got to college but there just seemed to be so little time and resource for the build to make it feasible. However, after finding this forum and getting help from many experienced DIYers and gaining access to the MIT machine shop, I realized that it is entirely possible for me to complete this project. All comments and inputs are welcome, as I am a beginner to EBs. So without further ado, let's get building.
Goals:
1. Build a light electric vehicle that can get me from point A to point B, using ideas and components that may or may not yet have been proven in other builds
2. Document this build and make it as comprehensive as possible so anyone reading this can build a working electric board from scratch (or as close to scratch as possible...)
3. Open-source all CAD parts designed after testing for open modification and improvements
MK I.5 CAD file release here (consistent riding around campus for about 4 months, more than 250 miles with little maitenance) *NOTE*: the hub drives are made to fit perfectly in thick core wheels, see discussion on page 4. Additionally, drawings are in metric so if things look ridiculously big, scale down by 25.4.
*Outdated* MK I CAD file release (successful testing of consistent riding around campus for ~3 weeks)
- 44 tooth Pulley and Truck Mount download here (A standalone copy of just the truck mount is provided on the bottom, but these two can be machined out of the same 3/8'' thick aluminum. The truck mount is designed to be a tight fit- as all Caliber truck cross sectional dimensions are subject to a small but noticeable tolerance- file/sand this down as needed for a perfect fit)
- Hub stop download here (Machine out of 3/8'' aluminum, you can also use thicker stock if you have the means to machine it)
- Outside retainer download here (Machine out of 1/8'' aluminum)
-Inside retainer download here (Machine out of 1/8'' aluminum)
- Motor Mount download here (Make this part out of 1/4'' aluminum, you can use 3/8'' from the truck mount's aluminum sheet if you don't want to buy 1/4'' sheet)
- Truck Mount individual download here (Make this part out of 3/8'' aluminum. I recommend milling the slot by 1/4'' but it's up to you whether or not you want the slot at all.)
4. Eventually miniaturize the whole board down to fit something as small as an Arbor Pocket Rocket
This was what the MK I board looked like in the very beginning lol.
