Been working on an Interchangeable Tool Mount System, Laser, Needle Cutter, Pen, Drag Knife.
This is not all original and is parts of several that I’ve found online and made a complete system.
So I finally got the STL files up on to thingiverse! So far I’ve printed the Pen/knife holder and the Needle cutter attachment, the Laser attachment will be printed as soon as my NEJE 2020 arrives… soon I hope! 
Some finishing between the matting surfaces may be required depending on your print quality I will also include the fusion 360 files if anyone wants them.
Pretty cool! I’d like to see pictures of them in use.
I would have had to put quotes around “Laser” though, ala Dr. Evil. 
Very nice!! Just what I need! 
That dovetail slide is the right answer. Did you make the dovetail tapered? Larger at the top so the tool plate snugs down right at the bottom.
No… it’s a constant size. There is no slope in it! It’s actually too tight when it comes off the printer and needs hand sanding as I wanted zero play.
