Planck Plate and Case (teensy based)

thingiverse

Human: * 03.2020 - A revised version of the plate has been uploaded, featuring a larger hole size for the "tab" key switch which was initially smaller than the rest, as well as correct printing orientation. These plates and cases are designed for a complete DIY keyboard, hand-wired with a Teensy2 controller. They fit on a 25*20 bed or bigger. The main characteristic of this plate is that it is stronger than usual 1.5mm Pla plates which are too flexible. The plate is made up of two layers: one 1.5 mm layer so that the switches can latch onto, and a second layer of 3.1 mm height with larger holes to avoid interfering with switch placement. This combination results in a very sturdy plate with a total height of 4.6 mm that does not flex. The holes for switches are rectangular, which works perfectly and also reduces print time significantly. There are dedicated holes for a costar stabilizer for the 2u key (which I don't find necessary at all; I use it without a stabilizer). The case is a minimal design with holes for screws and a dedicated spot for your Teensy under the third switch from the left. It also has a hole in the bottom to access the program button on your Teensy2. The holes for screws are 2.5 mm in diameter, allowing you to use self-tapping screws or 2mm, 2.5mm, or 3mm allen bolts (12mm-20mm length) with success. I have used both options successfully. Printing tips: * Print the plate upside down so that the upper part comes out glassy smooth and requires no support. * Use a brim for both plates to avoid elephant foot and improve adhesion to the bed.
