My wife was playing the pinball machine when I heard that dreaded sound of a relay constantly opening and closing, but nothing else happening.

On checking I could see the score was not resetting.
On checking the reset relay I discovered the fibre sheet that pulls the switch stack closed had broken.brocken_relay1.png

I do not have any spares for this and making a whole new fibre part would be a real PITA to cut out and I don't have the correct riverts so would need to buy or make them too.
SO the obvious choice was to just glue it back together.
If I just glued it, it would most likely snap again, so it would need support.
This is where my 3D printer came in handy again.

Three minutes with my vernier and sketchup and I had designed the part, and another 5 minutes the parts were printed.

I made them a tight friction fit onto the side of the fibre, so these with a drop or two of superglue and the part was fixed.

Its back installed in the pinball machine and its all back in action.
From broken to back playing took me less than 30 minutes.
Beats the hell out of a 2 or 3 week wait, waiting on the postman to deliver parts from USA.

Part is available to download on thingaverse

Yes really starting to love my 3D printer, all of a sudden repairs that would take me ages or be impossible without buying parts can be done now in anything from minutes to a couple of hours.
I have the sweeper arm for my score reel 90% modelled and when I get a moment will finsih it so I can look at fixing the score reels for the second player
