Specifications:

6.5 degree typing angle
Seamless design
HHKB blockers
Top mount plate (Plate Layout
More
)
Wedge bottom cover with sandblasted internal brass weight. You can remove it in case you plan to use a BT PCB.
Compatible with unversal pcbs (DZ60, YD60MQ, etc)

Base kit will include PC Top case, PC Bottom Cover with weight, and POM plate. You can purchase additional PC plates or Brass plates. All parts are sandblasted. No PCBs will be offered on the raffle, but I can include pcbs when the cases are ready to ship.

Acceptable Quality Standards

Bowing on the bottom cover. Since the bottom cover is connected to the top case via the four corner screws only, there is a possible .2-.3mm bowing of the bottom cover. This doesn't affect typing experience at all since the whole case will be 2mm above your table after addding the rubber bump-ons.
Minor scratches. Polycarbonate scratches easily so it is possible to scratch the cases during handling. However, I'll be handling the cases with utmost care during quality check and packaging.

Price:

Base Kit - 260$
Extra POM Plate - 30$
Extra PC Plate - 35$
Extra Brass Plate - 50$
Shipping Cost: Estimate is 50-80$ depending on the country. Courier will be DHL

Payments will be collected via paypal invoice. All prices doesn't include the 4.4% paypal fee. Shipping fee will be invoiced when the boards are ready to ship in order to determine the exact shipping cost.

Group buy Format:

30 slots that will be allotted via raffle.
GB form will be open until July 17, 10PM (GMT+8)
Invoices will be sent on July 18 and winners will have until July 19 to pay the invoice. Unpaid invoices will be cancelled and the spot will be transferred to the next person on the list.
No cancellations once the invoice is paid. If you're no longer interested in your spot during production, I will allow the selling of spots.

Timeline:

Estimated production time is 4-5 months (Manufacturing 1 prototype took 1 month). I don't want to promise a short turnaround and not be able to fulfill it on time. If it can be finished earlier then it's better. Please understand that there can be unforeseen events that can affect the timeline. Please only join this GB if this is acceptable to you.
I am not sure about the state of the world once the boards are ready to ship but as long as DHL can deliver on your country, I will ship the boards as soon as they are ready.

Terms and Conditions:

This is a group buy. The boards will only be produced after payment is collected from the gb participants. Estimated shipping time is after 4-5 months
The aforementioned shipping time above is subject to change. There are many factors that can affect the timeline of the production
No cancellations once the invoice is paid. If you're no longer interested in your spot during production, I will allow the selling of spots. Any fees needed for the transfer of slots will be shouldered by you.

Renders:

Some design improvements were done after acquiring the prototype. Below is a summary of these changes:

Decreased the bezels
made the plate screws m2 instead of m3 (same mounting points)
Added full backspace, full right shift, and stepped caps lock support on the plate (I forgot to reflect this on the renders)
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 to minimize bowing (please refer to the renders to see what I meant)

Note: Final plate design includes support for full backspace, fill right shift and stepped caps lock

Please take note that the renders are just representation and does not reflect the appearance of the actual product. Please refer to the prototype photos below in order to have an idea of the actual finish of the board.

Prototype Photos and Typing Tests

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://i.imgur.com/4ACq7i1.jpg). (More design changes can be found at the bottom of this post)
