Modular Filament Spool Holder

Remark

This thing looks like the design by filamentry (https://www.thingiverse.com/thing:2047554), But this no remix, rather a complete new technical design for much more stability at all by a solid corpus and distance connectors.

Print it

For every corpus two bearings 608 (see below) and two axes are neccessary. For holding one spool two corpora were needed.

For more stability optionally they could be connected by a connector, which is available for spools with a thickness from 40mm up to 75mm.

Two spool holders can be connected by the 2 Connect-Small. Also a CorpusDouble can used.for building multiple holders in row.

Build it

Maybe some filing or sanding is neccessary to the axis holes for putting in the axes. Mostly some smooth hammer hits also will help.

Bearings 608

Buy the cheapest you found or print it yourself.
