About this 3D model

One awesome tool for the home hobbyist that always struggle to stow your tools, made for cheap! 10€ including alligator clips, nuts, filament, hoses for atleast 2 of them! the nuts im using are the metric 18mm nuts for M12, they are usually 17,85-17,95 so my holes are 17,8, but that will keep the nuts in there. The time, dimension and material is for both center parts and 2pcs of the edge part, printed 60mm/s at 0,2mm layer
