I bought a piece of 1.5 inch stiff foam to try to fix a sag in a bed. It didn’t work but having that thick piece of solid foam around has been a life saver.
Need something flat to put a laptop on? Throw it on the foam. Going to be doing something that requires you to be on your knees for a while? Get the foam!
It went from stupid purchase to something I’d gladly replace if it broke.
I’ve really been resisting getting into drones via my 3d printer. I just love the idea that I could print out parts and make my drone better and better!
I only use it for things like guards, wire/cap/cameral holders… gopro case… things like that. but the frames are all carbon fiber. There are templates to print the entire drone out off the printer but I have not done that.
You can get the electronics pretty cheap. It might be a fun project for you :)
