The palette, parametric multiple hotends' base

A selector for your extruders. It is best used with vertical X axis. I have not tested it yet cause i don't have any hotends.
It mounts easily on your machine, in front of the big gear. You can mount up to 10 different hotends keeping palette's size reasonable.
I designed it with the parametric&multiple extruder(link).

I just printed one to see how it feels.i added alot of space so that the bowden tubes can move freely, but with 4mm tubes it could get smaller.
