Good day to you all,
As some of you might be aware sometime last year I released the files for a 3D printed friction drive. As time passed however I was getting increasingly disappointed by the performance of my (way too high KV) motor.
Roughly five weeks ago I decided to resume development and do it properly this time, by purchasing a 59mm SK3 motor (168 kv) and a 6S (2x 3S) LiFePo4 8400 mAh battery. New speeds and new motor weights bring new challenges so I hereby present you with the files for the beefy mount I've been using in the past three weeks.
The orange part as seen in the above screenshot is an adjustable limiter to allow you to fine tune the pivot angle. The other end is covered by a printed filter, to keep road debris from entering the motor.
The mount is held onto the 32.5mm frame tube with a pipe clamp which slides through the printed part. I'll look into taking a proper real life picture later today.
As before, the source files can be downloaded here. I've provided both STL and STP files.
Motor heat has been no issue with this setup, pushing me along at an (to me) awesome 30 km/hr. I do use grip tape for the motor as the roads tend to be wet quite often in this period.
Why share? Why not? This forum has taught me everything I wanted to know about bike propulsion systems.
