PTFE Tube rotatable Guide (magnetic)

This PTFE Guide is rotatable and magnetically attached to its base. The base can be fixed with a single screw or just with sticky tape. The top then attaches magnetically to the base and thus is freely rotatable to reduce resistance in narrow curves of the tube when the filament is rolled of the spool.

The base has a hole for any M3 or M4 screw (Spax). That screw fixes the base Magnet to the base plate as well. 

The top part has a 4.2mm canal with M5 thread at both ends. For smooth filament pass through I inserted a short piece of Capricorn XS PTFE tube between both fittings in the canal. The PTFE Tube for 1,75mm filaments can alternatively passed through directly.  In my case I chose to fix it with two Festo QSM-M5-4 (153304) Air fittings In the top part. The screws seen in the 3Dmodel are just placeholders for the M5 thread and as negative parts the are not printed with the model,
 

I mounted the PTFE-guide under a wooden shelf where I have hanging spool holders but it can be mounted in any other position as well. The magnets are strong enough.
 

My model was designed with Shapr3D and Printed in PETG with 0,20 layer hight and 0,40mm nozzle. PLA of course should be possible. I like PETG better.
No supports needed

For each guide two neodymium magnets 12x3mm (with a hole) are needed. One is fixed to the base by the screw.  The other magnet is glued with a drop of cyanoacrylate super glue into the top Part. In this way the top part can easily be removed i.e. when changing the filament spool.
