I modeled a couple of thread plugs with a 4mm hex socket and a wide flathead screwdriver slot. The threads were too narrow to pass a battery or accept a threaded plug. I need another revision, but the handle is coming together.
I updated the model so I could install brass coupling nuts as battery terminals, but I had a slew of printer errors. I cleaned and leveled the printer, and then I replaced the resin with new stuff. It still had problems, but I could test with one of the partial prints to ensure it fit a battery and a plug.
More prints failed, so I figured it was an issue with warping. I rotated the model in my printing software so the small flat side was the first layer, but I was using a resin printer, so it tripled the print time to six hours. The prints worked, and I could read voltage from a couple of brass couplers I installed as battery terminals.
I spent all day installing one of the battery grips. Getting the nuts in place on the inside, then spinning the bolts from the outside, was much more complicated than anticipated. I printed a strip of plastic that would hold the nuts while I tightened the bolts. It worked, but it took a couple of tries to get it right.
The last thing to make the tagger test-worthy was the power system. The batteries were installed, but they needed a step-up voltage regulator, and all the regulators in my stock were step-down. I found a usable one that converted the battery from 3.7 to 5.0 volts, but I hooked it up backwards in the tagger and broke it.
We discussed the first season of Dandadan and part of the second season, as it was not fully released on Hulu when we recorded. Amanda expressed a few criticisms and affections before her computer gave up, and she resorted to commenting with her phone.
The rest of the summary posts have been arranged by date.
