Another spool
by CCphoto

Description

Inspired by CCphoto's "Another spool" ( thingiverse.com/thing:8208 ), this spool is parametric, minimalistic, and designed to make changing filaments easy. To add a roll, hook the arm pieces around it, slide the rods into the slots in the arms, and tighten the nuts to clamp it. At the default size, it can hold a 5 lb roll as pictured, though it's probably better to use it with half the roll. On a Mendel, you could print one large enough for a 20 lb roll! It includes variables for the arm size and number of the arms (designed to work with 3 or 4, but 5 and 6 should also work) as well as the diameter of the bearings and of the rods.

I have included STLs for a version for m8 rod with 608 bearings and for the one I made, with m6 rod and some R188 bearings that I had lying around, both with 3 arms that will fit on a Cupcake's platform.

Instructions

Print 1 hub and the appropriate number of arms. Attach with threaded rods 9-12" long. I'm using it with my minimalistic spool mount ( thingiverse.com/thing:8472 ), but most mounting systems designed for other spools should work.

I just printed the spool cente, but there are the holes for the three sideway rods missing. I used pronterface to create the gcode. It showed a warning, that there is might something wrong with the STL file. Does anybody know this issue?

here you can see the problem, there no holes on the sides of the model. here it was sliced with slic3r.

this has been working very well for me, a month of use so far. I drilled a couple of holes to capture the filament for winding on (in the center) and another to capture the filament when not in use (on one of the arms). thanks 8-)

I added a little ring of Silicon sheet between one bearing and the washer+M8 nut to give a little resistance on the spool, this stops it moving too fast and unravelling.

I know my filament is very loose on the spool, but it's almost at the end, so the next roll with look great on it.

Where can these 20 pound rolls be bought? :)

Whoa! I just posted my version that I've been using since late January (Thing #8317) and now I see that you came up with very similar ideas about the spool hooks, which we posted less than an hour apart! Yours is definitely beefier than mine though! (I like only using 1lb rolls).

Nice design!
