Universal Spool Holder with quick On/Off-thread (quick release)

A week of use passed... (now 2022-08-28)

! works suprisingly well ! Super fast mount/unmount. Now I am changing spools "just like that". Am very satisfied with this design.

note: as there are three thread lines, if while at the spool it didn't grip immediately, simply rotate to the next thread line. One of three will instantly cach and grip perfectly.

I have happily used my https://www.thingiverse.com/thing:1122261 spool holder but the quick nut got broken. Then I have made a simple nut https://www.thingiverse.com/thing:2864509 and it worked for me faithfully for many years more.
But...
I always longed for the quick mount option (but I wanted some kind of simpler one) so I have built this spool holder.

This thing is designed from scratch. However as I used the same dimensions as thing:2864509 , I mark it as a Remix.

It works simply by pushing the nut on the "rails" till it reaches spool and then just tighten it by slightly screwing it on the thread.

If you found my design useful or inspiring and would like to buy me a cup of espresso you are welcome to tip me:
