After publishing the DOLCHpad, sohke shared a Planck-sized ortholinear keyboard in a 3D printed case made in a similar fashion – Dolothy.
I'm still not used to spray painting, and I'm not completely satisfied with it, but I finished building it anyway. It's an SLA 3D printed Dolch Planck board, and I named it Dolothy – sohke3.
The Dolothy40 or G80-1813 mini according to the author's other references was inspired by the Cherry G80-1813 – originally with 1800 layout. As in the case of these vintage Dolch keyboards, part of the luggable Dolch PAC PCs manufactured in the mid 1990s, sohke put the controller (RP2040-Zero) above the keys rather than on the main PCB area.
