Threadless ballscrew. 5mm, 10mm, and 15mm pitch

Closely based on MSollack's threadless ballscrew.

I made these basically just to test the concept, so they are fairly big and bulky.

The holding force is quite impressive and could easily be used for for many applications using linear drive

These are made for:
10mm shafts
608zz bearings
8x20mm cap screws and M8 nuts for the bearings
5x20mm cap screw and M5 nut for the clamp

They are available in 5, 10, and 15mm pitch

a cool effect of running different pitches on a single shaft simultaneously is that you get a telescoping effect through rotational drive (check video)

I'm planning on remaking these with smaller bearings and mounting blocks to make the more applicable for, say, 3D printers... more to come
