Don'be ashamed
, I didn't expected anyone could read it. The measurment are in l(liter) and mm(milimeter), my design is similar to the original Manger Zerobox 109 in measurment , only the outer and inner design of the box is very different. The box is made out of 13 sheets of 30mm thick MDF, each CNC milled, glued together and painted(very long process). There is no wall thinner then 35mm, on some places even 2x more.
The aluminium frame is milled out of 50mm thick solid piece of aluminium and covers the hidden spikes. The lines in each direction follow box.
