I really liked the original remix, but I needed mine to be a little shorter on the mount-part.
So I remixed it to use the bottom and middle screw-holes on the router mount, instead of the bottom and top screw-holes.
Also I wanted to use threaded brass inserts instead of printed threads, so I removed the threads - I do include a version with the threads intact, in case others prefer that.
Since I couldn't find a suitable bolt, I made an extra version for the M8 bolt I had, this one is only available without threads in the holes though.
Because the hole for the bolt is now a bit bigger, I made the entire thing 3 mm taller than before, so the dimensions don't get too thin.
The picture of the one I printed shows the M8 version with threaded brass inserts and M3 screws for holding the bolt and pen. Closeup shows the brass insert a little.
It needs all the same hardware as the original thing, plus two screws to affix the mount to the router mount. Set screws to hold the 1/4" bolt might look better.
This uses 1/4" 4" screw from home depot that has only small thread length at the end
- just cut out the thread and you have a perfect 1/4" shaft of 3 1/4 length for this project.
All other screws are 8-32
- the class 2b threads are perfectly realized in the STL, no need to retap."
