Hey folks ! So after doing a lot of research on existing open source pick and place machines I've finally settled on a design/machine style for my own. My design is heavily influenced by the brdmkr project here on hackaday, I really like the 6 rail gantry design and mine will be built very similarly. I am using 2020 aluminum extrusion and custom 3D printed joining parts to assemble the frame and gantry as well as pretty much anything. 

This is the frame design Im working with right now:

All those frame pieces are from my 2020 erector set project and be downloaded here and on cults3d/thingiverse, they are very sturdy parts, I print them with 35% gryoid infill and they are extremely stiff. This is all I've got so far, oh wait its gonna use TinyG for motion control and OpenPNP for overall system. 

Here we go again!
