This is a fully printable spool holder. (just another)

frame_wide.stl (140mm between bearing centers) is more stable for regular 1kg spools, frame.stl (100mm between bearing centers) supports smaller spools.

You need to print: 2 x frame or 2x frame_wide 4 x bearing 1 x pipe

for frame use 1.2 or 1.6 wall thickness

I managed to print in two prints frame and than bearing and pipe.

Bearings i took from https://www.thingiverse.com/thing:53451 and slightly modified.

NOTE!

Bearing middle fits into accu screwdriver bits and you must run it in drill until bearing move freely.

TIP!

You may put on bearing also some rubber band to escape slipping whel roll is empty.

Edit1: For frame holder haxagons increased diameter to bearings better fit.
