1/4 inch spring loaded "router bit" ink pen

thingiverse

I needed a way to operate my Maslow without wasting plywood, so I could check out some accuracy mods I'm working on. Instead of using pen holders as a replacement for the router, I wanted to keep the weight of the sled equal to what it is when cutting, so I came up with a small 1/4 inch "router bit" pen that can be swapped with a router bit and draw on paper. Needless to say, don't have the router turned on while using this pen. This pen is spring-loaded and utilizes standard ink roller pen cartridges.
