I bought bulk washing machine motors for millions of dollars and audio amplifier modules for a few thousands and N95 masks for a few hundred.

Also, take a look at ImportYeti.com

Redbubble lets you upload designs for t-shirts, phone cases, etc, and make them available in their web storefront. You only get a small slice of the sale price, but it's very easy to get your designs "out into the world."

I come up with mechanical designs as well as "artsy" things - which could be mass produced... but never like a logo-shirt or something as mentally ephemeral..

Right now I am modeling an 'thing' as a 3d printable (or injection molded at scale) attachment to a common house hold power tool, but can come in various grades (home|pro|industrial)...

I messed up and had a bunch of money in 2020 that I should have bought a printer with, but spent on stupid stuff like food and living expenses instead...

Other items are home-goods improvements/desires...

Think of me as the SamCo (Like RonCo) of my personal universe... but I am hoping some of that bleeds put into other universes such as xsmasherCo :-)
