Need somewhere dry to keep your filament but still have it easily accessible then you need to build yourself a filament box. You need a box big enough to fit your filament spools in. I am currently looking at making a box for 3 spools to fit in. You will require a length of broom handle long enough to reach across your box and you will need to print 2 x filament pole holders (1 for each side of the box). If the centre hole of your filament spool is 60mm then I recomend also printing 2 x filament adaptors for each spool to reduce it down to your pole size. For each spool you will require a filament duster and a small piece of sponge to fit in it. All these accessories are design to be screwed to the inside of the box. I have included the scad files so you can easily amend the parts to meet your filament needs. This is still a work in progress but I am currently printing the parts and looking to buy a suitable box and will update once I have finished. No supports required fro any part but would recommend at least 30% fill is used.
