Small Pulley - No Bearings Needed

Update 3/25/13 REV 1.5:

I made quite a few changes to the original design of the parts, for the better I think. I am planning on using the 3 pulleys that I just printed out on the job tomorrow. We are pulling a long section of fiber and are short handed. I am hoping to use these in place of some bodies. The plastic will be nice because there is very little risk of cutting into the outer jacket. I made use of the Acetone bath technique for finishing these pulleys. It looks like the acetone and ABS solution really helped seal the outer shell. I am hoping they resist cracking at the seams now. See the change log for more info and see the photos for the updated version.

REV 1.5**
Change Log:

  • Increased diameter of hole in the roller and frame. There is now minimal (almost no) post processing of the parts required.

  • Added a single roller to the design.

  • Removed decorative loop on top of frame

  • Decreased diameter and changed the shape of the end cap post to reduce overall post processing. End cap may require a touch of glue to stay secure now.

  • Changed to shape of end cap receiver in the rod to reflect changes in end cap post.

REV 1.0

I made this just to have something to play with. I might print another and hang my spools with them. As of right now this thing doesn't fit together with out some modifications. I had to ream out all of the holes with an exact-o knife and ended up glueing on the end cap of the rod. I am still new to 3D printing but I can see that this design does not compliment the material. It is still fun to play with though. Let me know what you end up using it for. I included the sketchup file. Feel free to fix and repost. :)
