Aquarium filter intake shrimp guard (for ø17mm pipes, e.g. JBL e402)

This filter guard has octagonal holes with a diameter of 1mm (maybe a bit smaller in the real print, depending on your printers accuracy). The dimensions overall are 102mm*50mm (the smaller one 92mm*50mm*). It fits on pipes with a diameter of 17mm, for example the JBL e402 filter.

Print with PETG or ABS only, as PLA would dissolve in water over the time. No supports needed!
