Quoted from Aniraf:OK, here are the details for the 3D printed hole protector. I'm not sure the Thingiverse link shows the pictures yet...but you guys get the idea from this thread: https://www.thingiverse.com/thing:4866580
If you're interested in tinkering with the design, you can do that here: https://cad.onshape.com/documents/40d82f709df95a983374ad60/w/dbaf121b6e644678ccd4d89e/e/a8652334283867e38030c7f9.
Make sure that you read my instructions in the Thingiverse if you print it. I'm not responsible for anything that could possibly go wrong from installing it or using it . Also, I would love any feedback about how it holds up for others people.
As for the PMs on selling it...I wasn't planning on selling it, but I could work up some numbers around the material cost, time and shipping. I honestly think shipping would be the most expensive part of it...but I might even be able to get away with just a padded envelope. Give me a few days and I can work up some kind of number that is both worth my time and not insane for the buyers.
Last thing I'll mention. I've got another 3D print solution that I'm testing. I have some friends coming over tonight to put it through the paces. If it works out, I'll drop that one tomorrow and maybe then there would be a reason to sell both parts together. I appreciate all the positive comments. I've never designed something for a pinball machine before and this is pretty cool .
Interested if you decide to make and sell.
