Dear Efferman,
First of all, i love your technical ingenuity regarding lego.
For my own build, i need a long linear actuator. I saw your gearrack actuator with a lengt of 11 studs. However sadly this wasn't downloadable on shapeways. Us there a possibility that gearrack actuator v3.1 Stroke 11 studs is free for download?
Thank you in advance.
