M42 to M42 macro extension tube designed specifically for 3D printing.
Firm grip for secure mounting
Textured internal surface for reduced internal reflections
Working aperture
Chamfered edges to counter elephant's foot
Chamfered threads for easier screwing together
No supports needed
PRINT SETTINGS:
Mandatory:
0.1 mm layer height

Strong cooling is needed
Carefully remove bridge platform after printing (see photo #5)
Remove all strings and loose particles after printing
