Hi everyone, I’m a first time poster here!
We bought a kit to build a robotic arm + mechanical claw and we lost one piece during the building process. The part number is 228-3446-250 but no matter how much I search for it in any kits or spare parts set in the store, I can’t find that gear.
It’s a 12T gear, about 9 mm tick or so, with rounded teeth on one end (see picture)
Anyone could tell me where to find it or with what else I could replace it (the thickness is important in that build)
