Apparently there is no real standardization in spool sizes. This vexes me.

I redesigned the spool holder to be much thinner. This also required the male/female brackets to be flipped and the female one now prints holes down.

It can support spools with inside widths of 52mm to outside widths of 107mm.


Again, i recognize that this is complete overkill, but I haven't found a spool that won't fit yet.

Print the male and female parts twice and one dust filter. Note that the dust filter now clips to the top support of the male bracket and the bolt for the bearings to prevent the filament from rubbing on the threads.

I used a 5/16" x 5" bolt since I couldn't find an M8 bolt long enough readily available.
The assembled order pictured is:


B - 608 Bearing
W - Washer
P - Penny washer
N - Nylon lock nut
H - Bolt head
R - Printed bracket

Would you be able to upload the source files? I built a sturdy version and need the hanger's to be wider.

Do I need to drill new holes for this holder?

Will this design cope with different spool diameters as well? That is, can it accommodate large diameter, (roughly 295mm or so) spools which are used to hold 2.2kg of filament as well as differing width spools which hold 1kg.


finally a spool holder that is compatible with all spools! I am so sick of changing the holder all the time! thanks :)

hello printed the dust filter but seem to be to big is it the wrong file?

No you have to clip the dust filter against the screw
