micro:bits are small, compact, and so powerful, which makes them an amazing tool for the classroom. However, it also makes them easy to lose or become disorganized. We 3D printed and tested 7 different micro:bit holders that you could use in your classroom! 

All of the files 3D printed and shown here were sourced from Thingiverse. Credit to each creator and a link to download the print files can be found for each holder below. 

All print files were printed on the FlashForge Adventurer 5 Pro using PLA and PLA+ filament.
