ESK8 Builds

Hi,

The purpose of this project was to find out if a electric mountain board could be made almost entirely with 3d printed parts.

After alot of testing i decided to use ASA/PETG/TPU plastics for this build.

3D printed battery case is made of ASA plastic, and i added “fast locking/release” mechanism for battery.

Sounds interesting, have any more photos of how this works?

I can record a video soon. Basically it’s simple locking mechanism. I tried various different versions and flexible TPU plastic worked best. It’s super strong and flexible.

Hi,

I can share files in a few weeks. I have to go through project and check everything is correct.

Very nice! I’ve always wanted to try printing with some of the stronger plastics but I keep deciding I don’t have the money to buy a roll :man_facepalming:

Your printed parts look well engineered, I’m really interested in your experiences with riding them.

Upload your designs, it’s never to early to go open source :wink:
