Grid based modular storing system (organizing and storing)

this is my personal grid system which i'm developing, the main grid uploaded is 20x20 cm with 4 little mounts on two of the corners to scew the grid on sufaces, this grid shall be printed at 1000% scale, no supports or raft, the boxes should also be printed at 1000%scale but if you want a snug fit on the grid i advice 1010%-1020% scale, print the boxes with supports and remove them after printing is done, this is a in development project and i will be posting new containers soon , feel free to add your own containers :) i printed everything in pla+ but this works with anything really

OPTIMAL PRINT SCALING FOR boxes:
(grid printed at 1000%)
-boxes that are 1x1 -->1010%scale
-boxes that are 1x2 -->1000%scale
