Filament dry box (2 spools)

prusaprinters

This are two versions of my filament dry box based on the IKEA 356+ 10L plastic boxes. Probably not that easy as buying a Drybox but a lot cheaper.These boxes are capable of holding 2 x 1kg spools at the same time (tested with varoious spool brands as formfutura, esun, filamentum, polymaker, dasFilament)Main part is the 10.6L IKEA box which costs about 9 Euro:https://www.ikea.com/de/de/p/ikea-365-vorratsbehaelter-mit-deckel-rechteckig-kunststoff-s79276760/ Version 1 contains a bottom mounted spoolholder where the spool is just held on by gravity.Version 2 contains a spoolholder which holds the spool by the bore in the middle.Both Versions work well. Its just a question of what you like more. The bottom Version has more resistance but also doesnt roll by itself. The middle version has very less resistance but can sometimes roll too much.It also works to use differen bottom mounted spoolholders  for example the original one from the prusa mini+https://www.prusaprinters.org/en/prints/57214-mini-printable-parts/files My main work here is the possibility to print from inside the box and the middle mount in version 2. You will need to drill holes into the box if you choose use that. But the holes shoud be sealed quite good by the printed parts. If unsure about it you could use silicone for extra sealing.Additional Parts needed:For the Filament pass-through you will need some PTFE Tube 6x4 (2x 8cm)For the standing filament roller you will need 4x M8 nuts,  2x 15cm M8 threaded rod and 4x 608 2RS (8x22x7) bearings.For the hanging filament roller you will need 2x M8 nuts, 1x 15cm M8 threaded rod and 4x 608 2RS (8x22x7) bearings1x Ikea 10.6L Plastic box with coversome silica and humidity sensors can also be used if you want but in my opinion this should only be necessary if you put PA spools inside. I have about 10 of those boxes since the bought parts are much cheaper if bought in bigger stacks ;)
