The YC66 Special - Gasket Mount, Thick Bezel Version

INTRODUCTION:
This is a poron gasket mount case for the YC66 plate and PCB. (I am not certain whether it will work with the Womier K66.)

N.B. I modeled the screws around M3 screws with a head diameter of 5mm, which I've belatedly realized is insufficient. Screws with larger heads therefore will not work.

PARTS LIST:

• YC66 plate and PCB
• M3 x 20mm screws x 12
• M3 nuts x 12
• Poron foam adhesive strip (2 mm thick, and either 3 mm or 5 mm wide) https://item.taobao.com/item.htm?spm=a1z09.2.0.0.67002e8dkmCU09&id=596691601583&_u=920rh52k32ea
• Keyswitches
• Keycaps
• Silicone/rubber feet (Optional)
• Case foam (Optional)

ASSEMBLY INSTRUCTIONS:
(1) Print out the case. If your printer's build volume is large enough, you can print out each half (TOP HALF and BOTTOM HALF) in its entirety. But I've also sub-divided the case into six parts (top left, top center, top right, bottom left, bottom center, and bottom right), in the event your build volume is too small to print out an entire TOP HALF or BOTTOM HALF.

Depending on the accuracy/tolerances of your printer, you might consider only gluing/binding the parts making up the lower half of the case, in order to ensure that you can properly align the screw holes on the bottom and top halves of the case. By contrast, if you also glue the top half together, it may become more difficult to align all twelve screw holes on the top and bottom halves.

(2) Apply the poron adhesive strips to the top and bottom halves of the case. You can either apply the poron along the entire perimeter of the case, or at discrete segments, according to your preference.

(3) Disassemble your YC66 (i.e., unscrew the screws). You will only need the plate layer and PCB.

(4) Install switches and keycaps onto the YC66 plate/PCB (if not installed already).

(5) Sandwich the YC66 plate between the top and bottom halves of the case and screw together. The distance between the top and bottom ledges is approximately 6 mm, and the YC66 plate is approximately 4.7 mm, so the poron on the top and bottom halves of the case will be compressed to about a combined 1.3 mm.

OPTIONAL STEPS:

• Add plate foam prior to installing switches.
• Add silicone/rubber feet to underside of case.
• Add case foam to bottom of tray.

TO DO:
Increase diameter of screw head model to accommodate more types of screws.
Add blocker to cover open top-right portion of YC66 plate.
Decrease size of bezels to reduce printing time.
Profile too high; need to reduce height of top half by about 2 to 3 mm.
Add space for internal weight.
Move USB cutout downward by about 2 mm.
Repair top center piece: currently, the ledge is not fully attached to the case.
Hide screws.
