About me and Polygon:I first joined GH back in 2016, when I started working on my first keyboard-design which unfortunately never became a reality as I lacked both funds, knowledge and experience.
Therefore, I acquired myself a Model M, which has been serving me well until earlier this year, when it died.
As I have design experience from the robotics industry, I decided to design myself a replacement which resulted in Polygon.
My focus was to create a keyboard that was different from the status quo, aesthetically. Whether or not i succeeded is subjective, but I think I managed quite well.Why the name?
Why the name I hear you ask? The many sharp edges of the weight is what gave it its name.
Oh, and also the supersized triangles machined into the bottom of the case.
Shout out to a fellow danish mech-lover Trip-Trap for reaching out to me when I was looking for someone to design the PCB.
We're excited to be showing off the PCB prototype soon.
Wall of renders Description
1 Custom knobA custom knob for the rotary encoder. It has a diameter of 25 mm.
It'll be available in any of the available colors and as a brass version.
2 The topThe top features a 3mm chamfer alle the way around the upper edge.
It has been given a slight fillet, to increase comfort.
3 The gasketsThe Polygon uses 12 lasercut gaskets. Not having the gasket surround the entire plate, will allow the plate to resonate slightly, and use the plate to create Polygons sounds signature.
The gaskets will be replaceable and cutting files will be made available if you want to experiment with gaskets.
4 The mounting systemThe mounting system uses four DIN-7 stainless steel dowel pins, and four linear low-friction bearings provide a precise fit of the plate in the case.
It also acts a rail allowing you to tune the typing feel by changing the gaskets for harder or softer ones or use thicker gaskets on one side or the other.
5 The bottomThe bottom houses the USB-C daughterboard and features a POLYGON engraving and my logo.
During assembly, the top and the bottom comes together to a form a single unit, the top and bottom is then fastened to the slope.
Six DIN 7984 low-profile bolts are used to secure top-bottom unit to the slope.
6 The weightThe weight is fastened to the slope, through the left and right acoustic chambers.
It weighs in at around 1.3 kg (2.86lbs). The sharp edges of the weight is what gives Polygon its name.
7 The slopeThe slope has 3 rectangular cutouts, used as acoustic chambers and will provide a unique sound signature.
The chambers can be foamed and tuned to your likings, using the provided cuttings-files. You will also have the option to choose my preferred dampening solution.

Layouts:
Each layout requires its own separate plate and PCB. The layout has been changed to accommodate wider support for more base kits.
It is important to me to provide you with the best product possible, which is way more feasible when the scale and complexity of the project is smaller.
This means that there are no plans of support for a soldered version of the PCB at the present.
ISO layout:![[IC] POLYGON 65% - Updated 19-10-2020: New layout, updated specs, exploded view 253920-37](https://geekhack.org/index.php?PHPSESSID=qa4fkrgj8p1qsg44uv2e1mdfdkujd55n&action=dlattach;topic=108832.0;attach=253921;image)
ANSI layout:![[IC] POLYGON 65% - Updated 19-10-2020: New layout, updated specs, exploded view 253918-38](https://geekhack.org/index.php?PHPSESSID=qa4fkrgj8p1qsg44uv2e1mdfdkujd55n&action=dlattach;topic=108832.0;attach=253919;image)
Things to do:
Finalize PCB-design
Gather feedback from the community
Order Prototype and color samples (PCB and case)
Test out the prototype (mainly mounting system) and order Rev 2 (Excited for this one!)
Order color samples
Experiment with gaskets and sound dampening
Change ANSI-layout to a more conventional one (6.25U spacebar, 1,75U right shift, normal backspace)
Changes made:
Moved up knob to improve usability and improve already dashing looks
The layout has been changed for wider keycap support
Additional notes
I will not be doing a polycarbonate version of the case because of quality concerns, when CNC-ing plastic.
I won't speculate on price or timeline yet, as I haven't ordered the first prototype yet. I will start the GB when I feel the like design is sound and solid.
That being said I hope to start the GB some time this year.
The design is subject to change and might be totally different when it reaches the GB stage. Please refer to the newest information.
The IC will be locked when the GB is started and the information there should be considered out of date!
Here's show renders showing off Liz' KAT PBJ modular keycap-set! Looking pretty, don't ya think?
Also please not that the case colours shown here are NOT part of the official [IC]. They do look good though.
