tinyurl.com/2s... This link will take you to my Google Drive folder which has 2 .stl files. One file is for the "Plus hole" for LEGO Technic axles which you can put in any object which you 3D print. The other file is for the 5x5 mm round hole for LEGO connections. We use Tinkercad to create or alter objects before printing them on the Weedo Tina 2 printer. Thingiverse has many LEGO parts
