How wide would you like your chastity cage?

I the next major update for the chastity cages will be additional widths. As the cages get longer the width gets wider.

This was my original size guide I worked from:

Length:                                              Width:

• Femto: 10mm                              33mm
• Pico: 20mm.                                 33mm
• Nano: 30mm.                               35mm
• Micro: 40mm                                35mm
• Milli: 50mm.                                   35mm
• Kilo: 60mm                                     35mm
• Mega: 70mm.                                37mm
• Giga: 80mm                                   37mm
• Tera: 90mm                                    40mm
• Peta: 100mm                                 40mm
• Exa: 110mm                                   40mm
• Zetta: 120mm                                 43mm
• Yotta: 130mm                                 43mm

This was based on other cages on the market finding a common theme. However, more variation especially with the width is requires. 

So if you could answer which width would work for you? I aim to start with 3 sizes for each length of cage. If the width you would like is not there, please comment below.
