Cabinet Door Damper Screw-Clamp Mount
This surface-mount block lets you add a cheap push-in soft-close damper to an old kitchen cabinet without drilling into the edge of the face frame. A 90° V-tunnel grips any damper barrel from 8 to 12 mm, and two M4 screws threaded into 3.4 mm pilot holes clamp it down. Four 4.2 mm slots for #6 wood screws let you slide the 46 x 44 x 27 mm block ±4 mm so the plunger meets the door.
4 in Duct Backdraft Damper Flap
A print-in-place gravity backdraft damper that drops into a 4 in (101.6 mm) round bath-fan duct: a 100.6 mm OD sleeve with a 94.4 mm hinged flap that the fan blows open and gravity swings shut against seven moulded stops, replacing the snapped or missing flap in an old exhaust fan. The 114 mm flange butts the duct end and carries three 3.4 mm holes for M3 / #6 sheet-metal screws; the hinge runs on integral 4 mm pins in 5 mm sockets, printed in one piece with 0.5 mm clearances.
