I redesigned the gridfinity baseplates with the idea of them being quick connect. Baseplates are held together with a quick connect clip from the top. Simply line them up and put a clip in place to hold 2 plates together. You can use more than one for more stability if needed. 

Every size up to 6x6 is included so you can print enough to fit whatever space you are trying to fit. 

Sized for gluing in 6mmx2mm magnets or 6mm head screws. 

Please note: Magnets are glued and not press fit. After ordering several batches of magnets and getting different levels of quality control on the magnets I opted to glue them in instead. the holes are 6.5mmx2.4mm to allow medium CA glue (super glue). 

Accuracy on the edges is important for the clips to work well. I advise cleaning your buildplate before printing.
