Summary

Need a travel cigar cutter that won't cause problems at the airport? Here it is, with a PLA handle and PETG blades, no supports needed.
The shells and the blade parts are glued together with superglue.
I suggest a layer height of at least 0.12mm and 100% infill for PETG blades.

Center_1 - N°1 piece (PLA)
Center_2 - N°1 piece (PLA)
Blade_2 - N°2 pieces (PLA)
Blade - N°2 pieces (PETG)

Printed with Ender 3 printer, 80% fill for the PLA parts and 100% for the PETG blades, 0.08 mm layer height.
