Case The main case consists of 7 layers of 3mm stacked acrylic, held in place by eight sex bolts, with an additional 2 layers for the feet providing a slight angle. The case itself measures 343 mm wide by 110 mm long (slightly less wide than a TKL), and utilizes a sandwich mount. PCB The PCB will be 1.6mm FR4, featuring a design on both sides by stellaidoscope. The PCB will only support original space invader switches. I plan to offer a silk-less option for the less cultured space invader enjoyers. There’s ESD protection, and USB-C, the PCB uses an Atmega32u2. There will be QMK/VIA/VIAL support.

Plates I currently only plan to offer 1.2mm FR4 plates, if you’d be interested in another material please indicate on the IC form. The only compatible stabilizers are original space invader plate mount stabs, and in order for the switches to clip in the plate must be thinner than usual.

GB Info Dates - TBD Colour options - TBD Vendors - TBD Price - target price for this kit will be in the ballpark of 100-150$ consisting of the case, PCB, plate, and bolts. This has been purely a personal passion project, and I just wanted to throw it out there to see if anyone else would be interested before continuing to invest my time in it.
Prototype Revisions The prototype case and PCB present no issues, although I did have some trouble with the stabilizer spacing for the big ass enter on the plate. I will be ordering a revised set of plates with adjusted stabilizer cutouts, and slightly shrunken branding. This is why the prototype photos aren’t fully built, and don’t happen to be using bolts.
