(moved) improved camera slider V2

THIS DESIGN HAS BEEN MOVED TO YOUMAGINE:

I tried to improve on the camera slider by Matt Roberts by making the sides more versatile.

You can mount the sider on a tripod now and mount equipment to it.

All holes for bolts and rods are tapered for easy assembly.
All corners that a human hand can touch are rounded.

V2:
I added M5 holes at a 45° angle into the feet, so you can insert threaded rods or bolts to dynamically add longer feet when needed.
