Canon EF/Ef-S macro extender

Hi, this is a 3D printed macro extension to turn your EF/EF-S lenes into macro lenses.

You can use any lens standard/telephoto. For tele lenses you can connect 2 extensions to achieve even bigger zoom.

Print settings:
Layer height: Any
Supports: Yes, but block the hole for pin.
Filament: Any, I used PETG because I had it on hand.
