A couple of weeks ago, staff member Elaine Bleakney posted this picture on our Instagram feed. It was captioned with an interchange she had with metals coordinator Ian Henderson, which mentioned the missing knob. (If you can’t read it, click on the picture to make it bigger.) Our friend Joe Lee (a.k.a. @clockfeathers on Instagram) suggested that someone could 3D print a new knob.
Joe follows Penland pretty closely, so he probably knew, from this blog or Facebook, that Ian (left) was half owner, with iron coordinator Daniel T. Beck (right), of an assemble-it-yourself 3D printer called a Printrbot.
Here’s the printer, fully assembled.
So Ian, who is quite the tinkerer, designed this knob in the 3D modeling software, which he had learned quite a bit about while working on this excellent project.
He sent the file to the printer, and here is the ultrasonic cleaner, made whole again.
