Friday, April 29, 2016 - VERSION 2 UPDATED
I have changed a few things in the model to make for an easier fit. Allows for more clearance between the M6 flat screw heads. If you've had trouble with the fit, give this new version a try!
These corner connectors are used to build the frame for the SmartRapCoreAlu. But, they can be used for any project that uses 90 degree corners and 2020 extrusion.
Needed (for each joint);
1 x printed connector
3 x M6 25mm Flat Head Screw (length depends on tap depth)
light oil for tapping
