This part sees a lot of action. I would've preferred PA here, but I still struggle with getting the quality I want of it, so this prototype was made of ASA. I did reinforce it from several spots to have as few 90 degree angles as possible in the parts where it flexes from ball hits.

Here's the PCBs back in place and the whole thing assembled.

I had bit of a skipped heartbeat moment, when one of the tiny C-clips decided to eject itself with quite a force. I could hear it hit my computer screen, keyboard and then land somewhere nearby. This time I could find it just after couple of minutes of searching. I need to source those from somewhere.

I'm contemplating on using Prusament PA-CF for the final version. I may have to play around with it to see how much shrinkage happens in print. The FreeCAD model is measured as precisely as possible and the idea was to handle the shrinking in slicer. ASA has so far been pretty much what went into the slicer so this project will probably end up being more of a learning experience than my average pinball parts creations.

ASA was surprisingly durable. I bolted one of the test prints onto a board and gave it some hammer to see how it fails. Typical parts I make never get these kinds of forces and I was pleased to see it needed some real effort to break this one, possibly so much that the ASA version would take normal use as well.

I think I'll leave the ASA version in mine and see how long it survives.
