The blueprint I provided is a mask, a copy of an archeological finding.
In case you desire to, please feel free to remodel it!

Good luck!

Step 1: Blueprint

for remodeling:

put the blueprint in a 3D-modeling software (for example SketchUp, Solidworks, Meshlap, Vector works)

(re)model it till it has the shape you want it to have

! make sure it is one solid model

safe it as a STL file

masker.stl

Step 2: Printing

printer:
Ultimaker

hardware:
I made my mask from PLA, but you can use any material that goes trough the ultimaker

software:
import the blueprint (STL file) in Cura

push: file > laod model file

my model changed when I imported it, so always:

check if the model is rotated well (the backside of the head
shoud be on the bottom)

check the scale of your model (163x126mm)

you can find the settings I used in the attached screenshots

! to make your mask smoother, you can lower the layer height (from 0.3 to 0.2?). It will take more time though

done with the settings? push ‘prepare’

Step 3:

check the layers by scrolling through your document

Step 4:

time to print! push ‘print’ (this screen will pop-up now)

connect

print

check the temperature

Step 5:

as soon as the printer is heated up the ultimaker will automatically start printing

“during the printing I had one problem. the printer started printing a two layer bottum. the bottum isn’t in the STL file, so there there is probally something wrong with the print-settings. I’ve no clue what it is! Maybe you will find out?”

Step 6: Finishing

to make the mask printable I added some support sticks at the file. Now the mask is printed out you can remove them.
a good way to do this is to use a warm, sharp object (I heated up a stanley-nife, this worked pretty well)
