The idea of designing a 3D-printable construction set has been on my mind for many years, and I am excited to finally be able to show you the first project made of STEMFIE parts. It is a simple example of a rubber-band-driven car. It is easy to 3D-print and build and fun to play with.
You can download all the files from the link below. Please let me know what you think of it. Through social media, I'll be following the hashtag #Stemfie3D.
I will release many more projects and continuously upload and share the complete parts. In addition, I'll use this newsletter and social media to announce new file releases.
I hope you enjoy 3D printing and building the STEMFIE car. Stay tuned!
:)
