Im curious as I usually use the site very occasionally to get certain electronic parts or order from PCBway like I just picked up some cheap but infinitely better than stock gps antennas for my LoRa T beams and im about to get a set of also still cheap but much better than stock 915mhz antennas but i kinda wanna throw some other projects or weird thing in the cart with it. It doesent have to be hobby electronics with soldering and all that but bonus points if it is.
If you 3D print, heat inserts. You can use them to insert metal threads into a printed object with a soldering iron to allow you to use standard machine screws in projects.
