Gridfinity Bosch LBOXX 136 baseplate

Im introducing the baseplate for gridfinity system for BOSCH L-BOXX 136 boxes. I minimized the edges so I could fit as much grid as possible (7x9). It also contains space for 6x1mm magnets. The baseplate is designed to be glued to L-BOXX by double sided tape. However, fit is just right and I don't think is completely necessary. 

I designed it to minimized the material as much as possible. No plastic waste ! It looks little bit flimsy but its sufficient inside the box and I don't think that is easily damagable. 

I printed it from PETG but feel free to use what are you comfortable with.
