    I would like this forum be an open discussion To find the best spool holding solution for RoBo.

    Ok. So I had my filament on a tripod next to my RoBo and I fell during a print snapping the filament off at the print head. So I'm thinking its time to either design a spool holder or find an existing design that will sit either next to or on top of RoBo.... (I prefer next to)

    I originally planned on keeping RoBo in my garage but I live in Florida which is very hot and humid. I was going to just hang the filament above it on a rod.... So I have changed my mind and will be keeping inside. Since it's going to be inside I need a more aesthetically pleasing solution to holding the spool.

    I was thinking something like this....

    The only issue I seeks that I will have to design some sort of filament guide to keep the filament from binding and rubbing on RoBo's case.

    What do you guys think. Do you know of a better option? Can you think of a better solution?

    I pretty much use something like what the robo guys have set up. A piece of pipe sitting on a couple blocks of wood. Easily handles any filament spool size. Its not the prettiest thing, but it works just fine. As long as the machine has a good filament feed, rolling friction is a non-issue. I think this is the 'best' solution because it takes zero effort to set up and costs nothing (made out of scrap material).

    That being said, I like the one you have posted. An easy mod to that system to make it more robo friendly would be to add in a fitting for a 1/4" flexible tubing then also add a similar fitting to the top of the robo as a guide.

    Is 1/4" the standard size used to guide filament? Is that the clear tube I see the filament going through on many RepRaps?

    I have a similar idea but instead of individual bearings that the spool edge rests on.... I want to put the bearings inside a tube and the I tube/cylinder will spin. We will still need to design a filament guide. RoBo has some unique challenges because of the case and the moving bed.

    I wa thinking of building a "dry" box to hold the spools but luckily in CA the humidity is fairly low most of the time so for now I am focusing on other things but wouldn't a bowden type system be more controllable I mean seems like it is a much less clumsy way to move filament around and keep it dry.
