Desiccant Filament Roller (updated and improved)

The original Desiccant Filament Roller is a very elegant model. However the roller had two problems:

1. It would not stick to the print bed.
2. It was a hair too long and so was rubbing against the case cover.

This remix has the original models for everything but the roller, which has been shortened by 0.5mm, as well as had some chamfer removed to provide a much greater area to stick on the bed with.

All the credit for this should go to RedFrez; I merely tweaked it.
