Absolutely Low Friction Filament Drybox using the Ikea 365+ 10.6l

I had a lot of problems with filament being stuck due to the higher friction of pulling out of the Ikea 365+ container and through 1.5m of reverse bowden. I liked the version created by AlexMu but there were things that I thought could be improved, hence I took inspiration and rebuild his version.

BOM: 

• 2x M3x20mm screws
• 2x M3x5mm(dia)x4mm(long) heat set
• 1x 4.75mm/3/16" diameter rod (you will need between 170-190mm depending on the height you mount the holder. The difference in length required is due to the fact the Ikea 365+ container is trapezoidal in shape)
• 2x 6mm OD 5mm ID PTFE tube  between 85-95mm long

Options:

• There might be an option to use VHB tape to tape the Inner Bracket to the wall of the container, but I have not tried that. This will probably significantly simplify installation but not sure how long it will last.
• The grooves holding the rods should hold up to 7mm diameter in total (rod + ptfe). Frankly even without the PTFE, the rods alone seem to result in very low friction. So if you are unable or unwilling to source both the 4.75mm rod and PTFE, you should do just fine with a bare rod up to 7mm. You will however will want to modify the dividers as they are currently made to fit on both the 4.75mm rod and 6mm PTFE tube.

• Remodeled from scratch and took into consideration the angled walls of the Ikea 365+ container
• Instead of a printed bar to hold the spool, opted for a single 4.75mm (or 3/16") stainless steel bearing rod to reduce the overall surface area/friction the spool contacts on
• Optional 6mm OD, 5mm ID PTFE tube which goes over the steel rod to further reduce friction
• Created dividers for the spools to prevent them from catching each other and causing any friction or jams.
