Various styles of terminal blocks for breadboards and robotics.
All can be printed without support.
I used 20% in-fill and 3 perimeters.
Standard size terminal blocks, in different styles/sizes. print, insert nuts, snap in metal connectors if desired, screw in a bolt or screw of your choice, wire something!

BB_mini_TB - Provides 16 terminals if all four corners are printed. Lower profile standoff columns.
onPRUSA_TB - Provides 10 terminals, mounts on an 8mm threaded rod.
