A spool holder for use within an AU$4 5L Anko food container as sold by KMart. Should suit spools with an inner diameter of between 50mm and 100mm, up to approximately 80mm across. Provided the assembly and mounting are correct, it will automatically adjust via gravity to the appropriate diameter.
Designed with 1KG spools and horizontal mounting in mind but may be able to support heavier spools. Not suitable for vertical mounting. Requires 18mm or ¾" holes in the lid and tub for mounting - use a spade bit for a cleaner cut as these containers are quite brittle.
A full unit requires 1x Post (Lower), 1x Post (Upper), 2x Sleeves, 2x Through bolts, 2x Bearing Cups, 3x Arm (Hole), 3x Arm (Peg), 3x Arm Clips, 3x Brackets, 3x Rods, and 6x Hands to be printed, with 2x 608 bearings. Optionally included is an externally accessible Winder, while a 608 bearing substitute is also provided (though the bearings give a better seal and smoother motion).
Assembly seems complicated but is relatively straight forward. While it can be done by hand I would recommend the use of a pair of pliers to assist.
A piece of gripping material can be fitted to the short L of the Brackets to better facilitate the use of the winder.
Final assembly pictured with 40cm of PTFE tube (4mm/2mm), silica desiccant, and a fresh 1kg spool of 3DFillies white PETG, using my previously submitted Mini PTFE Tube Grommet: https://www.printables.com/model/169677-mini-ptfe-tube-grommet
For a less complicated option, try my 20mm-60mm threaded variant: https://www.printables.com/model/169675-kmart-anko-5l-spool-holder-20mm-60mm
NB These Anko containers are not air tight. I highly recommend running a bead of something (silicone, hot glue, etc) to make a better seal.
Some of the parts of this Thing have very small contact areas and may require the use of a brim or raft to prevent them from coming up. This will primarily affect the Arm Clips and Hands, but can also affect the Rods and Brackets.
Dimensional accuracy is important. The parts which slide against other parts are designed to have just a 0.2mm gap on all sides, while the parts which grip together are 0.1mm.
I strongly recommended cleaning up at least the parts which will rub up against others by way of a pin file. Zits, shifted layers, or other surface artefacts in these areas can restrict free movement.
