Buildy Blocks

This is my new infinitely expandable blocks that have multiple positions from bottom to top. Every Buildy Block is 10mm in height and 20mm in length and width. But not for the top flat one. It is 6.552mm height and the rest is 20mm. If this model reaches a minimum of 100 downloads I will allow remixing and commercial use and add a 2, 4, and 6 slots and dots to the bunch. You know for my downloads. To reduce overhangs and for the parts to go in fully I made the bridge for the hole a cone and you can see an overhang spot in top on the Top flat.stl. Print this with 2 perimeters and 0% infill to reduce time wasting and wasting filament. (A trick from Joel Telling AKA 3D Printing nerd(3DPN)).
