Was looking for a tool to do wire-wrapping for fast electronic prototyping without the use of DuPont cables. All tools are quite expensive (~$20), so I decided to try to do one myself.
I wire-wrapped some projects using this, and the outcome is good!
The design is still in the works, because it needs to be printed below 0.1mm accuracy with a nozzle < 0.4mm, I don't have any of these.
But, still, it works generally speaking. The hole for the wire tends to be printed not-so-bad with the hardware configuration I have, but could be 'patched' using heat-shrink tubing.
