Description

A filament drybox for one spool of filament, keeps your filament free from dust and dry with the help of silica gel.

Several 3d printing filaments are hygroscopic, meaning they absorb moisture from the surroundings which can lead to poor surface finish and a clogged nozzle. Depending on where you live and what material you are printing with, moisture might not be that big of a problem. Dust however can also lead to poor surface finish and can result in a clogged nozzle.

You should always keep your filament dry and free of dust for a trouble free printing experience.

This filament drybox is intended for one 200 mm diameter roll of 1.75 mm filament.

Assembly instructions

		Start by inserting all the square nuts. Make sure there are no obstacles and that they are pushed all the way down. Use a small allen key or a flat head screwdriver.
		Don't remove the protective foil! Insert the brush seal into the “BaseFront”. One of the ends of the hole is chamfered for easy insertion, make sure you insert it from that side. Push it all the way in and make sure the whole seal is inside the part.
		Insert the laser cut clear PETG (is what I used) sides into the “LidSide” and “BaseSide” by aligning the end under the chamfer and simply dropping it in.
		Use the 12 mm screws to assemble the parts on one side of the “LidSide” and “BaseSide”. And slide in the rest of the clear PETG parts.
		Align the other sides and use the rest of the 12 mm screws to fasten them.
		Use the 25 mm screws and hex nuts to assemble the bearings. First insert the screw into the hole in the “BaseSide” and then start with the “BearingSpacer”. Continue “BearingSpacer2”, 608 bearing, “BearingSpacer3” and finally a hex nut.
		Place the assembled lid on top of the base and use the 22 mm screws and lock nuts to lock them into place. Make sure not to overtighten the screws and that the lid can move freely.
		Insert the magnets into the holes in the “LidBack” and “BaseBackTop”. Make sure they are in the right direction before you push them all the way in. As a final step fill and place the “SilicaGelTray” on the bottom of the filament drybox and you are done!
