POLYGON 65%
Long time no update
Almost 7
months has passed since i posted the initial IC here, and
boy has things progressed. Time has been flying delays have
been encountered, but Polygon has matured a lot in the
meantime. The third prototype is on its way, all the colors
have been revised, and the case has been completely
redesigned from the bottom up between prototype 1 and 2, to
meet my quality standards. It is now about time i show you
the prototypes I have, my new website and some various other
bits of information I’d like to share.

Pictures of prototype 3
I’ve gotten rid of the
wall of renders. It was a bit much.
Have a look at some
pictures of the real thing instead.

Description
1 Custom knob
A 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 top
The 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 system
The 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 gaskets
The 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 bottom
The 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 weight
The 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 slope
The 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.

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.
