Hi guys, I just want to share with you another design that I made. I never owned a pc board or a pom plate so I am curious about the sound and feel of this keyboard. I think many people are also curious since there a only a few boards that have this kind of combination. I decided to make it a 60% since pcbs for these are accessible. There will be only one layout for now and it will be HHKB.

Additional Renders (Outdated):
Side bezel is a little less thicker and added an angled bottom cover with internal brass weight


Prototype photos:
The quality of the prototype is satisfactory. This is my first PC board so I do not have a point of comparison. In terms of machining, the prototype was made according to the design files that I sent to the factory. All pieces fit and there are no tolerance issues.
However, there is slight bowing on the bottom cover due to the absence of center point screws ( https://imgur.com/VpeYkjS). The bottom cover is attached to the top piece only on the four corners. I didn’t put screws in the middle to achieve uniformity on the plate. The bowing is only .2-.3mm and does not affect the typing experience at all. Adding the height of the bump-ons, the bottom will not touch the surface of your table.
To mitigate the issue, I added an extrusion to the lower part of the bottom cover ( https://EnterEnter.oss-cn-shanghai.aliyuncs.com/geekhack/106062/4ACq7i1.jpg?x-oss-process=style/EnterEnter). (More design changes can be found at the bottom of this post)








Rev2 Renders:
Some design improvements were done after acquiring the prototype. Below is a summary of these changes. (This will be the final design when the groupbuy launches.

  • Decreased the bezels
  • made the plate screws m2 instead of m3 (same mounting points)
  • removed the curve on the front part
  • removed the 3 star and a sun engraving on the back
  • added a 3-star and a sun cutout on the weight
  • added an extrusion that will make the lower part of the bottom cover stiffer (please refer to the renders to see what I meant)
