I designed/manufactured playfield plastic protectors for my WOZ.
These are machined on a cnc machining center, NOT a laser cutter. The edges will have a nice, machined edge, not polished.
I make these using 1/16 thick polycarbonate, not the typical, PETG.
I have designed 4 of these, (both slingshot plastics, the inlane/outlane divider, as well as the "No Place Like Home" plastic.
Here is a pic of the protectors installed on my WOZ, as well as screen capture showing the plastic geometry in regards to the actual playfield plastic geometry, (magenta is the playfield plastic, yellow is the protector geometry). I offset the edges .100 where I could. You'll notice I'm not able to offset the edges where the ball drops, or it would interfere with the ball dropping out of the wireforms.
It's hard to see from the 1st pick, but I also didn't offset the edges near the flipper rubbers, so the protectors won't interfere with changing the flipper rubbers.
The 2 larger holes on both the divider and TNPLH plasics are clearance holes for the rubber stand-offs the JJP uses to mount the upper most plastic.
Price: $30 for the 4 piece set, SHIPPED anywhere in the continental US.
Any interest?
