Hanging filament spool holder

For my "Filament wall mount brackets for duraline f-system" I needed some sturdy spool holders to print directly to my Prusa MK3.

V1 only supports 22mm tube, new V2 will also support 3/4 inch tubes.

V1 comes in 4 sizes

• A 55 mm wide spools, for fillamentum for example
• B 70 mm wide spools, fits most the spools
• C 80 mm wide spools, for slightly wider spools.

D 90 cm wide spools, needed for wider spools, like prusa includes with their printers
### Update November 25 2018

As requested many times, it's now possible to create custom sizes for everyone. To do this I redesigned the spool holder in Fusion360, using parameters everywhere.

I need to know 4 main parameters
A - Spool size (diameter)
B - Spool hole size (diameter)
C - Spool width (left to right)
D - Tube size (diameter)

The design then calculates all sizes including tolerances, chamfers, etc.
If you choose a larger spool holder, smaller spools will work as well. So choose the largest you have if you don't want to print multiple.

V2 Sizes
199-50-69 T22mm + 199-50-69 T3/4inch | Real
200-52-56 T22mm + 200-52-56 T3/4inch | Filamentum

V2 Requests:
220-85-65 T22mm + 220-85-65 T3/4inch | Unknown, user request. Quite large diameter. Will fit multiple brands
195-38-80 T22 | Unknown, user request. Small spool hole diameter.

My other two spool holder designs are now also updated to be used with 3/4 inch tube!

### Features

You can easily remove them with one hand, while a spool is still on

• They come in multiple sizes
• You can get an empty spool holder out of sight by moving it
• You could mount 4 (or 5) next to each other to support Prusa's Multi Material upgrade!

Print instructions

Category: 3D Printer Accessories Print Settings

Rafts: No

Supports: No

Resolution: 0.200

Infill: 30%

Notes:

Printed in Orange ABS to fit my Prusa MK3.

You should use 30% or more infill since there will be 1-2 KG on there...
I used a 5mm brim to ensure the ABS does not bend/comes of the plate. There is nothing left of this after the print since there's a chamfer underneath.

Uses about 18-20 meters of ABS and took around 4 hours to print one. (V1)

How I Designed This

Used OnShape to create this (V1), took some revisions to get all dimensions right and balance use of material vs. strength.

Then redesigned it in Fusion360 (V2), fully based on parameters to easily resize it on request
