@FreeCAD This week, I released the first beta version of my parametric 3D-printed morse code key. It is a set consisting of a key plus various kinds of mounting or holding arrangements. Screwed down to a desk or block, strapped to your leg, or held in your other hand.
Almost everything about it is parameterized with VarSets for ease of customization, and I wrote a macro to export STEP and STL variants with different built-in 3d-printed springs from light to heavy tension, different lengths of sliding covers, different heights above your leg for the leg mount, and more.
Designed in local builds of FreeCAD 1.1 dev running on Fedora 41. Licensed liberally CC-SA to let others modify and share their modifications.
