Spool holder with PTFE connector

I own a Qidi X-Max 3, which has the filament feeder at the back, including a dry box that is attached to the back of the printer.
The printer stands in the corner of a cabinet, under a shelf board. It is almost impossible to use the dry box where it was intended by the manufacturer.
To make it easier for me to load filament, I connected a longer PTFE tube to the back of the feeder, which is routed to the front and attached to the dry box there. The box then stands freely next to the printer.

When I print with PLA, I don't necessarily need the dry box. It is more important to me that I can change the filament quickly and easily. In this case, a simple filament spool holder is more suitable for me. However, this must have a connection for the PTFE tube, which makes things a little more complicated again, as there are far fewer models of this kind available here on Printables.

I have therefore created this very simple filament spool holder, which has an M10 connection for a pneumatic push-to-connect fitting to which I can attach the PTFE tube.
So far, this solution has worked very well for me, which is why I am now uploading the model here.

I've printed my holder from PETG, using 6 walls/perimeters and a 25% gyroid infill.
