Do you own a Delta 6" Professional Joiner? Did you recently move? During the move, did the movers break the joiner depth setting knob? If you answered yes to all the questions, then this thing is for you!
Actually, my wife and I recently moved, the movers broke the depth setting knob on my Delta 6" Professional Joiner, and I designed and 3D printed this replacement. The photograph shows the old broken knob, and the 3D printed replacement installed on the joiner (with the initials "GLZ"). I printed the prototype at high speed (150%), and at .2mm layer height with 10% infill, so it appears a little rough, but it works. I had planned on printing the final version at standard speed, .2mm layer height with 100% infill, but the prototype worked just fine.
I seriously doubt anyone will download or even print this thing, but I posted it to show that if a 3D printer is good enough for making certain replacement parts for a professional woodworking machine, who knows what's next. I can imagine in the future replacement parts are only a download away.

The more mistakes I make, the more knowledge I gain.
