PTFE tube filament support holder

I couldn't find what i was looking for to support the PTFE filament tube, so I made my own.

There are 3 parts, a wall mount which is effectively a cradle screwed to the wall, then one of the two guides can slide in place, the fitting can be a little loose but a piece of paper or thin card holds it in place without putting too much strain on the printed parts.
The guides come as 2 types the first is a simple flexible guide for the tube the second features a funnel to help easily guide the filament into the tube, these move to allow flexibility for the filament feeding from either side of the spool without forcing the filament to bend too much.

After printing the ball part may be slightly stuck in the outer part, rotating the ball will free it up
