These are some remixed parts for the Otvinta Servo-Driven Digital Clock.
Modified STL files for the parts that require contrasting colours. They have been setup so they can be printed with an M600 filament change gcode or with a multi-colour printer by selecting the different parts of the STLs and assigning them to the extruders.
The original project suggested either gluing the shoes on, attaching paper or card or using a multi-color printer. While you could cut the existing STL files to add the colour change I wanted the extra vertical lip so made these modified versions.
While not part of this remix, I additionally ported the electronics for the project to an ATmega2560 based microcontroller to remove the need for Windows IoT, Raspberry Pi and Pololu Maestro controllers. You can download the microcontroller code on Github below.
Arduino code for controlling the Otvinta Servo-Driven Digital Clock
The repository also contains more detail on the other electronics used and suggested links for vendors (most components are available from a wide range of sources).
When printing the modified parts, the M600 should be placed at the following locations in the gcode (if you don't have a tool to do it automatically).
- Segments - after layer at 1.2mm is complete
- Center - after layer at 44.6mm is complete
The Otvinta clock is a great build and lots of fun, I highly recommend it as an enjoyable build. Please support the original author so they can continue to put out such great projects.
