Spool barrier for "Filler Filament Holder"

EN:
One of my first remixed models resulted in a large model file of almost 30mb. I therefore redesigned the thing to reduce the file size as much as possible. It fits into the holes of the “Filler Filament Holder”  with ball bearings, which serves me well due to its low rolling resistance. However, you sometimes need a barrier to prevent the roll from falling down. The “Thin spool adapter” from Daniel is suitable for the very narrow spools, for wider ones I have designed this barrier here. Anyone who has ever had a bobbin fall off the roller during printing will appreciate such a barrier.

Material: PLA
Layers: 0.2mm

Eines meiner ersten remixten Modelle, ergab eine große Modelldatei von annähernd 30mb. Habe daher das Ding redesignt um die Dateigröße maximal zu reduzieren. Passt in die Löcher des "Filler Filament Holders"  mit Kugellagern, welcher mir gute Dienste durch geringen Rolwiderstand leistet. Allerdings braucht man auch manchmal eine Barriere, damit die Rolle nicht herunter fallen kann. Für die sehr schmalen Spulen eignet sich der "Thin spool adapter" von Daniel, für breitere habe ich diese Barriere hier entworfen. Jeder dem schon mal eine Spule während des Druckes von der Rolle gefallen ist, weis so eine Barriere zu schätzen.
