Description
1 – Custom knobA custom knob for the rotary encoder. It has a diameter of 30 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 mounting systemThe mounting system uses four 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.
4 – The gasketsThe Polygon uses 12 molded 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.
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 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 1.1 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.

All prices without shipping.
These prices are unfortunately higher than the first estimates based on a quote from the manu. I recently asked for an updated quote that unfortunately came with a very significant price hike due to the current metal prices.
I am very sorry about this.
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.
IF YOU PLAN TO DESIGN YOUR OWN SOLDERABLE PCB PLEASE READ: You will need to make at least 6 switches hot-swappable. Send me a DM for details.

Things to do:• Wait for case Prototype 3
• Wait for PCB prototype 3
• Announce GB date and price within this month
• Ship the prototype out to reviewers
• Crack a mildly amusing dad-joke
Changes made:
• Completely redesigned the inner workings and fits to meet my quality standards
• Added engravings to the plate
• Changed the typing angle from 8 to 7 degrees
• Lowered the whole case to increase typing comfort
• Increased the knob size to 30 mm
• BIGGER Polygon logo and made the weight protrude slightly more. It also covers more of the back now.
• Optimizations made to the gasket system.
• Seamless sides
• Triangle engravings have been added to the inside of the case as well
• Added automotive-grade curves for seamless transitions from corners.
Additional notes
I will not be doing a polycarbonate version of the case because of quality concerns, when CNC-ing plastic.
Unfortunately the price has been subject to change as the metal prices have been rising according to my manu.
