C270 Support for Ender 3 Pro base

First thanks a lot to Waverunner62 for very good design of sturdy camera mount (Merci beacoup).

I needed a base for my 4040 profile Y axis Ender3 Pro 3D printer.

I made few changes of the design because the idler has more tight clearance to the metal holder so I made it with a channel and I decreased the clamp inner distance because it was too generous. Of course the height of the base is increased to comply with Ender3 Pro Y axis roller. Also a Fusion360 model is added.
