Nespresso pod racks

I used it screwed to the underside of a cabinet but should work well on a wall too. I drew out the screw holes on some paper as a guide for drilling but you do you. Screw holes are 4mm.
Dimensions:
6 row - 280mm x 194mm
5 row - 236mm x 154mm
4 row - 192mm x 194mm
please let me know any suggestions you may have for improvement or if the models are too big and I can make a smaller one still.
