Here is a Version of a mini Spoolholder. This Version is for Bearings.
This Version is for M5x20 or M5x25 Screws (mine are to long with 30mm :D ).
The Size of the Bearings are: Diameter: 16mm / thickness: 5mm / Hole-Diameter: 6mm (M5 Screws).
I used also 2 washers between the Holder an the Bearing. thickness of the washer is: 1mm.
On the Bottom of the Holder are two Holes for fixing the Spoolholder with small Screws.
Hope you like it.
Enjoy and happy printing.....
