I’m thinking of making a dry box for my printer, however I have some questions:

  1. Will using PVC pipe as a “roller” (if that’s the right word) that I’ll place my filament spools on be good enough? Or do the spools need to go on something more concave? Maybe I can cut some grooves for the spools to sit in? I know there are dry boxes that use like holders that you screw in, but I want to limit the amount of holes in the box.

  2. Does filament have to be spaced or can I put the spools in the box to where there is no gaps but they can still move freely?

  3. Does it matter if I use M6 or M10 pneumatic couplers to feed the filmanet through or is it just personal preference?

    I mean if it’s working then it’s probably fine, two tubes would be interesting, I would think that would be a hassle when you have to take it in and out to change the filament. I ended up switching to using rollers on the bottom because of that anyway. I was going to try that one I linked before but I started designing my own similar one that used 1/2” EMT and bearings as rollers, I should finish that hah.

        Yeah that is similar to what I was thinking but 4 individual sets of rollers, one for each spool. This version would be annoying in a drybox because all of the filament spools will probably spin at the same time which will make them all unspool since you will probably have them fed into 4 couplers and not clipped like on a shelf. Might work though if you don’t plan on having one output for each box and switching the “active” spool but I try to not open my dry boxes in general to keep air moisture out.

          Ah thanks for the input…I didn’t think about all spools spinning the samed until you mentioned it so I just decided to print the individual rings that I would put the bearings in then I’m gonna put them on a metal rod.

          Also not sure you would know, would i be fine printing the bearings to use or should I get metal ones

            I have never tried it but I am real curious for low speed things like that, I think it would come down to your printer being able to print something small enough. There are a bunch of print in place bearing designs on printables that I have run across too.

            I usually use 608 bearings for that kind of thing because they are really cheap on Amazon as well since those are used in roller skates and skateboards and stuff. I am definitely curious though so you should reply if you try it out :D
