I've decided to create simple chess clock based on RP2040.

Clock dimensions 190mm x 80mm x 50mm

Top is designed for 2x 24mm arcade push buttons. On the back there are 3x 7mm holes. I used them for Mode and Play buttons (7mm Mini Momentary ON OFF Push Button) and for on/off switch (Toggle Switch 1/4 Inch - MTS102). Front is designed for two 0.56 Inch 4-digit 7 segment digital clocks (TM1637) and they fit perfectly. No glue needed. The mount part is for Li-Pol TP4056 microUSB charger.

Supports are required for the front of main housing part. It took around 15h to print Top, 4h Bottom, 2h Front, 30 min Mount which gives around 21h in total.

All parts are glued together with hot glue.
