Knife scabbard / sheath / saya

Prints in vase mode with brim. Set 0 bottom layers and if you want 0 top layers - I did, so blade has ventilation, to prevent steel oxidation.

I printed it using PETG, with 0.6mm and increased extrusion width to 0.8mm.

Attached is STEP file, you can adjust if needed.

I'm using it for some time now and it's great. I put small amount of camellia oil to steel and it's no issue in contact with PETG.
