Little MasterSpool Extended

The original Little MasterSpool was to small for Fiberlogy REFILL filament. I broke 2 spools while trying to lock them, so I remixed it and extended columns by 3mm. Now it is much easier to lock the spool using the "click" mechanism and there is no need to secure the spool with filament to prevent self opening (but of course it is always better to secure it anyway, everything can happen :D)

Printing time: ~2h50min (on 0.3 layer height)
Filament needed: ~50g
