Split Spool Holder 30mm for CTC

Sometimes it is necessary that parts are not too high, so I decided to design a spool holder, which is divided into two parts.
The diameter is 30mm, so the spool holder also fits for the lion & fox filaments, which have an inner diameter of 31mm. The standard spool holder is too thick.

The threads in 0.2mm resolution will work.
Easier and better they work in 0.1mm resolution.
If you like, you can stick the parts by the thread in the middle.

All threads are "easy fit" and should work wel
