It is a holder for a KATANA, my friend has two. The middle one is 105mm from the base to the circle. The other two is minuss 40mm therefore 65mm, the other is 125mm.

I used PETG but most polymers are fine.

Infill: 5%

5 is plenty, the sword's weight will hold it down.

Perimeterss 3:3:3

I included a STEP file and Fusion360 file as well if you wish to modify.
