Tools

Small tools for the jobs that come up every week: a box, a hinge, a gear, a kerf, a file to look at, a robot to check. Free, in the browser, with no account.

Click the ratio to step it from 1 to 3: the right gear keeps its teeth and the left one takes that many times as many. Drag a grip on a pitch circle to add or take away teeth; the arrow keys step both.Involute teeth of the same module mesh: the centre distance is the module times half the teeth of both.

Each one a click away

These jobs are done in the editor itself: each card says where, and its link opens it.
