Consider to follow if you like what I do.
Just ask if you have an idea to a lego piece you want to be made.
Lego track rods or links in sizes up to 15L. This a new version. The old one suddenly fell off after the PLA had dried for over half a year
I can make +0.5L too, send me a message if you want it.
Apply a lot of force to mount, and they dont fall off easily.
