My first attempt at using PLA as a support material for PETG. I have these square-sectioned holes coming from the side, and I need the top surface to be fairly accurate. Bridging usually has enough sagging to cause problems. Plus there are round overhangs at each end, which won't print well at all without support.
I modelled these plugs to be pre-printed in PLA. Then placed them in the PETG par

Here's the finished device in action. It's used to load primers into a feeding tube, for #reloading ammunition.
A lot of similar devices have a built-in vibration motor. But I'm cheap, and I figure everyone has something around the house that will serve the purpose. A massager. An electric toothbrush. Some other sort of... device... that vibrates. None of my business.

New food-grade grease. $23 from Amazon, and it comes with enough grease to do 2 or 3 mixers. Only comes with one gasket, though.
Everything degreased and reassembled. Old grease has to be removed, because it was full of metal particles. These machines are supposed to be regreased every few years anyway.
Stripped out gear on the left. Replacement from Amazon on the right. The Chinesium replacement is not quite to the same level of quality. Slightly rougher finish. Straight out the die casting machine, I think. But it's pretty good. Also co…
I'm quite impressed by the build quality of the #KitchenAid stand mixer. All metal construction. Metal housing, metal gears. Easily disassemblable and repairable, in the event your in-laws somehow manage to overload it and damage it.
