Electronics shelf sleeve placement

[menthol1979]

Hello ! First of all, many thanks for your work! It is absolutely marvelous and I decided to build one. However, I have a (stupid maybe) question. DIY Machines places the electronics shelf on top right position. Based on your diagram, since your design starts at lower left, where this module should be placed? On position 0, position 15 or position 7?

Thank you!
