Moonveil Katana - Elden Ring

Note: please read Chapters Printing Notes and Assembly Instructions

Update: I uploaded a custom vertical wall mount designed specifically for the Moonveil Katana! It’s the perfect companion to complete your Moonveil display setup!

After my recent Elden Ring upload, "Site of Grace – Elden Ring Diorama", I wanted to show the game a bit more love – so I recreated the iconic Moonveil Katana in full real-life size! It’s the weapon my character wields in-game, and bringing it into the real world as a detailed 3D print was an absolute blast. 

This is a 3D-printable replica of the Moonveil Katana from Elden Ring, designed for display or cosplay use. The model features decorative silver inlay slots along the blade and guard, which not only serve as striking visual elements but also add internal structure to improve alignment and strength during assembly. The katana is about 135 cm long (53.15 inches).

That said, it's still a PLA print, so please treat it as a decorative prop—not suitable for swinging or combat simulation.

If you plan to use it for swinging, you’ll find uncut STL files for both the blade core and the matching inlay plates included. This allows you to modify the stl and insert carbon rods for additional reinforcement.

Printing Notes

I highly recommend using the provided print profile — it's been thoroughly tested and gave me great results. If you really want a Version of the print profile for A1 mini, tell me!
The blade segments are printed standing upright on their cut faces. This makes build plate cleanliness and adhesion critical.

• If you're experiencing issues like layer shifts or poor bed adhesion as the height increases, try reducing your print speed.
• On my X1C, prints worked fine on the first attempt using the included print profile without tinkering with any settings mid print.

Assembly Instructions

If you're planning to paint the blade, do it before assembly. Avoid getting paint on the glue surfaces! Paint can interfere with bond strength.

Refer to the included labeled diagrams for part names and orientation. 

Here’s the general build process:

Blade Assembly

1. Start at the tip of the blade with parts A and B.
2. Glue the blade cores A + B together using PLA glue or superglue.
3. Once the core begins to hold, attach the matching inlay plates A+B (left side) and A+B (right side) to align and secure the blade.
4. Continue by attaching blade segment C, then plate B+C, and so on in the following order:
   • D, then C+D
   • E, then D+E
   • F, then E+F

 At the final plate pair (E+F), you might find the fit imperfect due to minor tolerances. I observed a ~3–4 mm overlap. Use a precision flush cutter (the kind used in model-making and 3D printing) to trim off the excess – the cut blends well with the texture and won’t be noticeable (see image). 

Guard and Grip

• Parts F + G form the guard. Two sizes of alignment dowels are provided – the smaller ones fit more smoothly. The dowels are just for positioning and shouldn’t require force to insert.
• Grip parts are joined as follows:
  • G + H
  • H + I

Before gluing the grip, test the alignment to ensure you're not gluing any part upside down or facing the wrong way.

Grip Wrapping

To wrap the handle, I used a flat cotton ribbon, approx. 10 mm wide and 10 meters long (about 0.4 inches x 33 feet). You can find similar ribbon on Amazon.

This was my first ever grip wrap, and I followed this YouTube tutorial. I skipped most of the tools and simply wrapped it tightly by hand, which took ~30 minutes. The result looks much more authentic than any printed grip pattern could.

Enjoy printing, Tarnished!
