Would like some feedback on my first attempt at designing a keyboard

[akwdk9]

 Hello everyone. I am relatively new to this hobby (About 7 months). I could get Fusion 360 for free with my college email, and thus I have had a go at designing my own original (kinda) keyboard.

 The internal structure is basically a carbon copy of the Bakeneko60; since this is a personal project and I don't really intend to GB this or something (Even if I wanted to, I probably can't since I copied an existing product), I thought I could just get the PCB and plate of the Bakeneko60 and use it. And it is obviously gummy o-ring mount. However I cannot confirm that the PCB from Bakeneko60 will actually fit, since I do not own an accurate model for that PCB.
 
 The exterior design is 'inspired' by Keycult No.2, QK65, and F1-8X 722 (which I am a proud owner of). Simply put, It is a tofu with some grooves.

 I have attached the STP file to the post, so feel free to download it and take a look.

 Below are some specs:
-Layout: 60%
-Typing angle: 8 Degrees
-Size: 310*108*34 (mm)
-Front height: About 18mm
-Mounting style: Gummy O-ring
-UDB C3/C4 compatible

honestly don't do an one off its gonna cost you a lot to prototype and get something you like

What would be holding down the PCB/Plate?
Assuming the plate is at where it will mount, I see about 5.7mm from top surface to plate's top surface.
This would expose the keycap. (keycap's lowest point would be higher than top surface of the case)
Plenty of space on the bottom side, so it wouldn't interfere with PCB.

For the size, normally, PCB should be smaller than the plate, so if you can fit the plate it should be able to fit your PCB.
However, if you are using specific PCB, I would buy the PCB before you request manufacturing the case.
Also, the case at this point would require at least 5 set-ups in 3-Axis machine.
That would bring the price up quite a bit.
