2020-04-05 (Su) Electro Knife for Simulated Combat EleKSCo

Yesterday, I thought about the problems with gluing switch adapters to the tops of plastic tubes because when attached, they encase the switch nut, and the only way to get them apart is to destroy them. E6000 held well, but it takes hours to cure, and service during a knife fight only affords a couple of minutes. I wanted to try a model that leveraged bolts instead of glue, so I updated the switch adapter with countersunk holes.
New design with screw/bolt holes

When formatting in Cura, I expanded the model to 105%, a peculiarity of my printer, and set the infill to 100%. I experimented with less glue on the platen, and the result was a clean top, whereas my previous prints were a bit ragged there. I worried that the countersinking holes would collapse or be the wrong shape, but they turned out splendidly.
The bolts sit flush with the top of the adapter
