This is a spool holder for A1 printers. If, like me, you no longer have the spool holder that came with your A1 printer

It is also designed for 2-kilogram spools, although I don't have any spools available for testing at the moment.

There are two versions:

No accessories required:

This is the default version, which doesn't require any additional accessories. Simply insert the PTFE tube into the tightly fitting hole at the front of the bracket.

Includes accessories:

This version changes the PTFE installation hole to a threaded hole to accommodate PC4-M6 accessories. This makes the hose more secure, but it requires additional components. This is the version shown in the photo, but both versions have been tested.

It can be printed on an A1 or A1 mini, but the finished product is only suitable for A1

Trimming the PTFE tube to make it slightly shorter can reduce its bending degree, which may also be beneficial.
