Lots of other spool holders out there as well. Thanks for the help Raise community.

We must give to Caesar what is Caesar's ; it's Sylus solution :mrgreen: remix from a ultimaker user design
and photohoolic reports in the forum few days ago...

i didn't experiment printing problems linked to that but it's good for the noises (no spool that rubs on the door anymore) and it improves the feeding because there's absolutly no friction... even if i don't visually notice an improvement

One thing i've not told you is that on my first printer (from october 2016), the spool holder were in metal and heavy... i saw that on the last printers, they are in plastic and lighter and so it's less stable (i never used this plastic raise3d spool holder because i had 2 metal ones)[/quote]

I love remix things ,this shape was my favorite UM2.
Next level now....

I will probably be printing that design, however has anyone tried it in the top spool holder? My copy of it went in easy but was almost impossible to remove. Not an issue with the lower spool holders. I am printing my one with a smaller extension so it can be removed from the top location.

So my spool holder now works, but it really isn't much of a reduction in friction from the original. My one used 0.3 N while the stock one used 0.5 N. I was expecting a larger gap in measurements but that is what I got, remember that the error in these measurements is probably about 0.2 N so the values are fairly close.


My spool holder 0.3 N

Raise offset spool holder 0.5N

What did however really surprise me was the friction increase after I fed the filament through the
small filament holder tubes was a large 1.1 N force !

So I am now working on a sleeve to replace the filament tubes

When looking at my other 3D printer the Raise tube is almost half the size.

The mystery of the phantom frictional forces continues. :)

For some Filaments it is a really good idea to make an outdoor spool holder. I tried CarbonX on R3DN2Plus andstuck after 30 each time. because of the high buildplate temp the room gets too hot and makes the filament soft. And feeder stucks. Some PVAs have same effect.

Are there any designs with ball bearing based spool holder ?
