The filter cones are design according to ISO 5356-1:2015 standard, with FDM 3D printing technology in mind.

This version need no support at all, the locking tab is separated, so can be printed flat. This make it very strong. Easy to assemble – just click in. Once assembled it’s hard to disassemble.

The initial idea comes from:
https://www.thingiverse.com/thing:4248511

Print parameters:

• Material – PET-G
• Nozzle max 0.4mm
• Layer max 0.2mm
• Perimeters – 3 to 5
• Top/bottom layers – 3
• Infill density – 40%
• Infill pattern – Concentric or Grid
• Seam position – Random
• Solid Infill Threshold Area – 70mm2

Best result could be achieved with adaptive printing parameters set. Print parameters adjusted for different adaptor areas. For detail ask in comments.

For massive production print separately adaptors and tabs.
