This design is a tribute to my beloved Labyrinth. Knockers are available with or without mount holes. Print the Knocker and KnockerSwing separately then flex to assemble. Supports are required for the KockerSwing and are pretty helpful around the Knocker’s swing hole.

Mount hole diameter specifications are precisely calibrated to two good sized screws I found in my random parts bin. Knocker Tool is a quick print to help match screws, confirm scaling size and install screws for mounting. The knocker and swing scale down cleanly to 25% but still looks pretty neat as small as 15%.

The Speak No Knocker is available on Cults3D (https://cults3d.com/en/3d-model/home/speak-no-knocker) or through my Pateron exclusives (https://www.patreon.com/merganmcfergan)
