3d printed friction shifters


Whoa! Durability testing?


mashing the like button so hard my mouse spontaneously combusts


Also trying to quantify the clutchfeel with the strain gauges. So far, it’s testing the lego’s durability.

Also been working on an idea for a one piece bar end clamp


turgid in this thread too




You probably know this, but “clutch power” is what the lego friction fit is called.

I once handled a neat stack of about 30 non-production 2x4 bricks that were stacked in order of clutch power. The top ones fell off with a breeze. The bottom ones required tools to separate.


oh this is nice.


Make it go faster!

I need a set of these for my wife’s 3x8 winter bike.


Any update on when I can buy


This project is so cool


Just posting to say that I too would like to buy these


Thanks for the interest, all. I had to take a break due to mental health SNAFU. Starting to get back into it though.

Are you thinking one-handed robot pusher/friction dangler collabo because I love that idea. DT require some thinking and changes to the parts stack since it goes into a frame boss instead of something I control.
