My name is Leo and I'm from Hong Kong. My hobby is 3D printing and building robots.

I run a blog called '20sffactory', meaning a factory out of 20 square feet, utilising 3D printing, low cost microcontrollers and software, I host a project called 'Community Robot Arm', which is a free & open collaborative project in a Facebook community to build and improve an open source arduino/ESP32 robot arm.

This project and community took a lot of time to develop and maintain, any sponsorship will mean a lot for me to acquire new electronic parts and continue its development with the community.
