Tenkeyless Keyboard with 2 Port USB-Hub

Here is a picture of the 3D printed case before finish.

I actually printed it in 5 separate parts that i than glued together with epoxy. Did this because of the limitations of the pint-bed size and because i didn't want such long time prints. (I have a Wanhao Dupilcator I3 Plus btw.)

After printing and glueing i than pushed in threaded inserts to connect the PCB to the case. Than i sanded the print smooth, filled bigger holes/print mistakes with filler, sanded again, sprayed it with primer and than put on the color (RAL9016) and a coat of clear varnish

2 and last mistake with the schematic was having the ground connection of the encoder on the wrong pin.

I made a upsi in the schematic with the USB-Hub Chip. I pulled-up a configuration pin, instead of pulling it down to GND. This changes the USB hub between buspower and selfpowerd.

I added a cut-out in the housing for a metal weight.
I calculated it to be 450g in copper, or 570g in lead. To make the keyboard make fell more solid and make the sound better.

Had to remove some material at the housing around the USB-C Port. So that no material has to be removed with any tools after 3D-printing.
