Bed 85
Layer 0.3

Speed 40-45
Time for printing 8 pcs (for one spool) - near 14 h.

The spool is tapered, so the top and bottom are different. Recesses for neodymium magnets 6х2 (as drug) are made in the boxes (they need to be glued), on the contrary, screws are screwed into the spool.
This is necessary so that the boxes do not open at the same time when only one is needed.
The connection is made with a piece of copper cable with a diameter of 2.5 mm, which is bent from above and below after installation. The spool must be pre-drilled.
For multi-storey system you should print Bottom part (1pcs) and Top part (2 psc for each next).
During the printing, you must stop printing before 22-23 layer (insert M0 in G-code after 21-22 layer) ane put the female screw M6 in the ready-made recess, than continue printing.
All parts are connected by a long threaded stud for M6 screw.
