2021-10-18 (M) EWC_Panel Second gen prints

The captive button cap idea I started with seemed innovative, but Washover resin completely locked every piece I checked. At a larger scale, it might work, but I want tight tolerances so nothing wiggles. I cut up one of my prints, and there was resin locking the cap to the chassis. I redesigned the model, so the shaft had a flared bottom, and the top had a tapered nub. The top disc had a matching socket, so I could add a drop of resin to them and make them captive after printing and curing.
Reshaped plungers arranged for printing

I had problems with one of the chassis prints. For some reason, the support pieces didn't adhere well, and as it lifted off, the print warped. I threw this away, but the one that printed right on the platen turned out well. The discs I added and printed with supports also turned out clean. The chassis on the print surface was tidy on the outside. I didn't put any supports on the interior, so a few interior layers drooped and flaked off. Since this part won't be visible or interfere with operation, I will keep printing them this way.
