I notice SF has a few beginner kits, tool kits, resistor kits, ect. Why not add a small screw hardware kit for beginners? I just went nuts (no pun intended) trying to find the right hardware for my robot. I know they sell individual screws but sometimes you just need to look at a box of them to find the right one. And it would be nice to be able to get some small/medium acrylic or Plexiglas sheets while there, make it a one stop shop!
Actually, there are hardware places online (can’t think of any off the top of my head right now) have kits like that. They just have a random assortment of nuts, bolts, etc. Also, I’ve seen similar at Home Depot and such.
