Homemade fencing reel

[babaroga]

I am running small fencing club in Bosnia and Herzegovina. Of course, main problem is price of scoring equipment so I decided to spent some time and try to make my own.
Here is some pictures of my fencing reel. This is fifth version and result of approximately 2 years of development. Everything was drawn in FreeCAD and printed on 2D printer. Cost of material for one reel is around 35 USD. I used 4 springs from chainsaw starter.

Here is some videos of reels in action.

Unfortunately, FreeCAD file is too large to upload on forum so here it is:

I used PDN, with lot of body cloning which kind of worked with some tweaking. All bodies are positioned manually.

Wow!! Very great work. And totally functional.

Thank you!

I am printing second pair right now, and all parts will be same color !

It can roll 20 m of cable with more or less constant force.

Did you design the Arduino score machine with Freecad? If that is the case you should include it in the post...

Great project, nicely done.
Thanks for sharing the file. I briefly reviewed it and I am curious.
Did you move the Body to its proper location before creating it or after? In other words, did you create the body in-place or at the global origin and then move it?

Nice project and thanks for sharing.

No, I did not. It was Inkscape+DraftSight. But you gave me idea to do it also in FC.

As you can see from file name it is version 5, subversion 3, so some bodies I copied from other (older) file and aligned manually. I was not aware of this possibility before, but it opened whole new world to me. Others I draw in place. Anyway, only thing I rotated and moved were bodies as such.
