A matching filament spool holder belongs to the noble Tukkari case. However, the 1 kg Tukkari holder has a definite disadvantage in my eyes. The very thin shaft is not on bearings, so it happens quickly that the spool shakes when it is spooled off. My ball bearing spool adapter effectively prevents this shaking.

The adapter can be mounted with two ball bearings size 6000 on the 10 mm shaft of the Tukkari holder. The bearings are installed on the inside of the adapter, therefore the adapter is also designed in two parts. So that the adapter does not shift on the shaft and the bearings also do not slip further inwards, a corresponding clamping piece is mounted firmly on the shaft under the adapter.

Specs

Fits spools with a minimum bore diameter of 50 mm and a maximum width of 70 mm. When the adapter is used in combination with the 1 kg Tukkari holder, the spool can have a maximum outer diameter of 250 mm.
