Spool holder

Just another filament spool holder but with the incredible cool biohazard mark! :)

The frame parts should have pretty much infill to make them stiff. I used 35%.
If you have problems with warping use the "Frame_Brim". The small brims are easily trimmed off with a knife.

You can choose how many bearings you wish to use depending on the type of filament spools you have. Just put Bearing Replacement parts (B_R_x) instead of bearings in any configuration you want.
It's actually possible to use the spool holder without any bearings with just B_R parts but it will have a little more friction.
There should be a M8 washer in between every part on the treaded rod.
OR you can print an all plastic version using parts "Holder1" and "Holder2".

The things you need to build this are:
Printed parts of course.
A piece of threaded rod, 105mm long, 8mm (M8) diameter.
2 Nuts (M8)
608 bearings
Washers M8
