I made this as a very simplistic way to support a spool of plastic over my RepRap, since I'm short on desk space.

It works just fine with charlespax's nice cardboard spool design:
I have now also designed my own printable spool that will fit on this stand:

The slot at the top takes up to a 10mm shaft, while the slots at the bottom are sized to grab hold of the top 8mm studding on a RepRap Mendel.

It's designed to require as little assembly as possible, and you should be able to make one out of wood too, although that might be a bit wasteful, as it's also designed to be lightweight.

If people really want it to be secure on there, then I'll make a design with flanges to bolt on with something like a y-bar clamp.

The included bushings are for gluing to a cheap cardboard spool so that if you use threaded rod it doesn't cut away at the cardboard.


Print out two frames, do any cleaning necessary on the bar slots, sit them on top of the reprap, put a bar through your spool and rest it on top of the stand. Easy peasy.
With the latest (1.3) design, you can also clamp the stand in place with bolts instead of zip-ties or string or whatever else you might use with the others.

When I convert your .stl files to gcode, skeinforge gives me the following error a bunch of times:

This should never happen, there is a hole in the triangle mesh, each edge should have two faces.
1310 [750] [354, 455]
Something will still be printed, but there is no guarantee that it will be the correct shape.

Is it possible there are holes in the stl's?

So far, it hasn't kept me from printin
g the stuff, and it looks good, but I bet there are small blemishes somewhere because of the hole.

Just thought you'd want to know, in case you need to tweak something in your software/design process.

Thanks so much for the useful designs! :)


Skeinforge apparently is apparently coded to ignore a lot of problems with STL files generated by SolidWorks, which the later software Slic3r doesn't although it has many other improvements. A lot (but not all) of the problems can be fixed by running STL files through NetFabb.

Also holy shit you have a similar name to me, and I forgot to reply to this O_O

Update 2:

  • Improved the feet a bit more, now they should be more rigid, and by not being so far down, easier to clamp onto the bars with a zip tie.

  • Altered the bushings to make them easier to ream out by adding thumb grips and tweaking the inner diameter.

Update 3:

Something I've been meaning to do for a long time, making the stand so that you can bolt it down tightly instead of using zip-ties.
