Assembled the device
Here all I did was get all of my 3d printed parts I made and screwed on the pcb into the base and put the top/knob onto it. surprisingly it all fit perfectly together and after flashing the code into it, it all works now so I can say that the project is done.

Soldered all of the components to the pcb
(Ignore the bad solder joints they look way better now)
Well after getting my soldering iron and all of the components I started to solder them onto the board according to the schematic I made. I applied flux onto the parts of the pcb I would solder the component to and then solder it on. This took me about 45 minutes to do.

Hey! Cool hackpad, I loved the design, but there are a few changes required. You need to connect the SCL and SDA pins of OLED to the SCL and SDA pins of Xiao, respectively (pins D5 and D4 ). Also, please have the source files of your CAD model in the repo!
