Pasta Drying Rack Hub For 8 mm Dowels
A six-arm top hub for a homemade pasta drying rack. It drops onto the end of a 3/4 in schedule 40 PVC mast (26.7 mm OD, 27.0 mm blind socket) and holds six 8 mm wooden dowels in 8.3 mm sockets, 28 mm deep. With 250 mm dowels you get a rack about 600 mm across. The hub is 92 mm across and 40 mm tall, and the socket roof is a 45° cone, so it prints without supports.
Flagged: contact with food. Not for safety-critical use without independent engineering review.
Servo Horn To 8 mm Shaft Hub
A pinch-clamp hub that adapts any screw-on servo horn, disc or small wheel to a plain 8 mm shaft — the 44 mm flange carries four radial M3 slots spanning an 18–34 mm bolt circle, so it fits round and 4-arm horns without guessing their hole pattern. The 22 mm boss has an 8.3 mm slip-fit bore with 27 mm of shaft engagement, split by a 2.2 mm pinch gap closed by a single M3 screw and captured nut; 45° gussets tie the boss to the flange and the clamp ears ramp at 45° so the whole thing prints flat on the flange with no supports. Overall 44 mm diameter x 34 mm tall.
