Many school printers are designed for filament spools of one standard size. However, one way for schools to save money is to buy spools in large bulk sizes.
However, these large bulk spools will not fit in / on the factory spool holders.
You will also need a scrap section of 1/2 PVC pipe or dowel. I've used a broken broom handle as well.
I designed this to fit the large 2.2 kg (5 lb) spools from colorfabb. This is high enough to give you clearance for any commercially available spools.
This is designed to fit in the channels of the extruded aluminum frame of a Lulzbot Taz 5 / Taz 6. It is a great way to use the vertical space above the printer.
Your students can use this on their Lulzbot, or as a stand alone external spool holder for school printers.
This can be used to explore architecture and geometry. It can also be expanded to hold more spools of filament.
UPDATE: THE SPOOL OF THRONES version of this holder can hold 6 of your tools close at hand. I've had a couple spools get tangled, and I could never find my wire cutters when I needed them, so I put some tool slots in spool holder to hold them close by.

This is a large piece, so watch for warping.
Break all sharp edges after printing. The pipe should fit snugly inside the holes, so use sandpaper to smooth out the insides and outside of the pipe.
If you have a MOARstruder, this would be a good project to test the thicker layer heights.
This is a work piece, so I just use a soddering pen to smooth down any sharp edges. Sand the inside hole and pipe so they form a snug, smooth fit.
This was designed in AutoCAD 2014.
It was designed to fit in the channels of the extruded aluminum frame of Lulzbots. This is designed so I can use the large spools and still have the vertical clearance I need with my Taz 5. This can work as a stand alone spool holder as well. These give me easy access to the spool compared to having it on the side of the printer.
Students will provide service to the school.
Students will maintain 3D printing equipment.
Students will explore arches and triangles in architecture.
Students will explore stress, distributed load, tension, and vibration.
High School, Vo Tech, and college level students.
The properties for these files can be explored in solidworks or other professional CAD program.
Students should understand basic geometry.
Students should understand force, loading, and dynamic forces.
Students should understand how 3D printing works, and how to troubleshoot common problems.
a. Students should review geometric shapes.
b. Students should review dynamic loading and static loading.
c. Students can test loading by standing on these spool holders. They can compare the forces involved to what computer models predicted.
d. Students can use solidworks to predict and measure stress and loading on them.
e. Students can explore redesigning these to be lighter, use composite material, or have other desirable properties for 3D printing.
f. Students can explore ways to commercially produce these holders, or run a printing farm to produce enough for all the schools printers.
Students should demonstrate knowledge of 3D printing techniques.
Students should produce functioning spool holders for the school.
Students should understand dynamic and static loading.
Students should modify these to meet the engineering needs for their printers.
