This is an adjustable filament spool stand that I have used on a desktop next to a printer and inside my filament dry box. The aim here was to make something that could accommodate nearly any filament spool and was easy to swap spools out.

For one stand you will need to print:

• 1 x BodySide-WithThreads
• 1 x BodySide-NoThreads
• 1 x AdjusterScrew
• 1 x AdjusterScrewLock
• 4 x BearingWasher
• 2 x Rail

You will also need the following parts:

• 4 x M3x4 bolts
• 6 x M3x12 (ish longer is fine) bolt
• 4 x 608 ball bearings
• OPTIONAL: adhesive rubber feet (there are nice to keep it from being able to slide around on hard surfaces but not required by any means)

Assembly

• Insert the rail pieces through the body side without threads so that the long end is sticking out the side with posts
• Insert a short M3 bolt and through the top of the hole on each of them and secure beneath with an m3 nut
• Insert the adjuster screw through the same body piece you just attached the rails to so that the length of it is sticking out the same direction
• On the inside of the body piece slide the adjuster lock over the divot in the adjuster screw and then secure it to the body with 2 longer M3 bolts and nuts
• Add a 608 bearing over each of the posts on the inside sides of the body pieces, securing each by placing a bearing washer over it and then fastening a longer M3 bolt with a nut through it. I like to secure them with the heads of the bolts on the outside of the body but it does not matter much here.
• Slide the body side with threads over the end of the rails such that the bearing sides are facing each other and twist the adjuster screw to get it started.
• Adjust to the desired width via twisting the adjuster screw.
