A 60 mm OD × 18 mm wide spoked drive wheel that slips onto any 5 mm motor shaft (NEMA 17, 37 mm gearmotor) and locks with an M3 set screw threaded into the 6.3 mm hub wall. The 8 mm × 2.5 mm rim groove seats a #64 rubber band as a tire, and 24 scallops in the flanges give traction if you run it bare — replaces the hub-and-tire set nobody stocks for one-off robot builds.
A flat kitchen paddle with four graduated holes that measure dry spaghetti for 1, 2, 3 or 4 servings, plus a ribbed grip and a hanging hole. 141 mm long, 4.5 mm thick, dishwasher-basket friendly.
