А где купить детали?

[@Ballanux]

I don't sell the pieces, you can download them from the link in the description and 3D print them. If you don't have printer, you can order in some 3D printing services online

Thanks is simple and effective, wonderfull I´ll redesign it for my telescope but the working principle is simple and great thanks

Усилие страгивания гораздо больше усилия продолжения движения. Туда бы фторопласт. Возможно подошла бы фум-лента.
