I'm currently restoring my first pinball machine and the plastic under playfield parts for my Ball Kicker Unit were in a terrible state and to the best of my knowledge you can't get replacement parts for these, so I decided to 3D print replacement parts.
Fifteen minutes with my vernier and a scrap of paper and another 30 minutes on Sketchup and I had the part modelled.
Ten minutes later I was ready to fix the replacement part to the pinball machine.
I'm reasonably happy with the results and over the weekend will print the other 3 I need.
Got to love the fact that someone used nails to fix the other parts to the underside of the machine............
I've also uploaded the STL file to Thingaverse should anyone else want to print some.
Anyone else used a 3D printer to make plastic parts you can no longer get?
My printer is not good enough to make parts to go on the top of the playfield that are visible, but great for bits like this.
