Nagumo Weapon Reavel

This is my favorite from Sakamoto Days, Yoichi Nagumo. But I should go into that now. Here's the steps on doing it correct

Print at 100% infill with a layer height of 0.08mm with a base layer of 0.16mm

The Model is 186.92x200mm in size
You may print at higher layer heights below the Base Thickness of 0.48mm
The Max allowed Thickness is 2.24mm and the Actual Thickness is 2.08mm

Filaments Used:
    #000000 PLA BambuLab Matte Charcoal  Transmission Distance: 0.6
    #545454 PLA BambuLab Basic Dark Gray  Transmission Distance: 0.6
    #9b9ea0 PLA BambuLab Matte Ash Gray  Transmission Distance: 1.5
    #ffffff PLA BambuLab Basic Jade White  Transmission Distance: 5
This print uses 4 unique filaments

Swap Instructions:
    Start with Charcoal
    At layer #8 (0.72mm) swap to Dark Gray
    At layer #13 (1.12mm) swap to Ash Gray
    At layer #20 (1.68mm) swap to Jade White for the rest.
 

Now somethings wrong with it in the meanwhile, but if you know what problem it is. Please say it to me
