MasterSpool System for print beds as small as 100x100mm
The parts are connected with 6 m3x20mm bolts and nuts
The forks are now split into two pieces, which makes mounting the spool way (!) easier. a slight bevel makes for a sturdy connection of the parts. The end of the spool can be clamped down with the arms. The spool holders now uses 3 m3x20mm and 3 m3x16mm bolts and nuts.
I used 65g of plastic in V2 of the spool
To reduce the risk of entangled filament you can either pull some left over filament through the extra holes in the arms, or you can cut out two disks of sturdy foil and add them next to the sppol the way I did in the photos
