Ghost mask skull

Ghost skull mask ready for 3D printing.

This is a digital stl file.

Mask consists of 3 parts - face, back and hat.

Parts should be connected using magnets - location holes are included in the design.
Assembly notes included in the zip file.

This item is for personal use only and resale of the printed item/s or the 3D files is not permitted.

Just a friendly reminder that the files are for personal use only - not for resale.

Size :

Here are the measurements that were used when the mask was created.
If you need to resize, then your formula would be :

Target Size / Original Size = scale ratio

Height from under the chin, to the top of the head : 270 mm ( 10.6" )

Width measured inside, just in front of the ears : 188 mm ( 7.4" )

Circumference ( hat size ) just above the eyebrows and above the ears : 660 mm ( 26" )

Magnets :

Neodymium magnets

There are 7 sets of holes ( 4 for the mask front / back, and 3 for the hat )

Depending on the strength of your magnets ( 'N52' being the strongest rating ), you may be able to use magnets on 1 side, and a steel nut on the other.

If in doubt, just use magnets in both parts as they are not expensive.

Magnet hole sizes are 7mm, so look for 6mm ( 1/4" ) round magnets, or 5mm cube magnets. Either should fit well.

All magnet holes are open thru holes so you can use magnets of different sizes.
This also allows the epoxy ( or whatever adhesive you use ) to push the air out of the back of the hole.

Attaching Magnets :

From my experiences, I found the following procedure to work quite well :

Start with the front of the mask.
Use a metal plate or coin that the magnet will stick to.
Place some masking tape on the coin.
Stick the magnet to the coin.
Place some epoxy in the hole.
press the magnet ( attached to the coin ) in to the hole.
The air and excess epoxy will exit thru the back of the hole.
The coin will keep the magnet flush with the front of the magnet hole.
The tape prevents the epoxy from sticking to the coin.
Once it is set, remove the coin and the tape.

For the second side ( the rear of the mask and the hat ) :
Place some tape over the magnets in the front of the mask.
Place the second magnet ( or steel nut ) for each joint on to the tape covering the first magnet.
Add epoxy to the holes in the second part, and then press the second part on to the first part.
The magnets will go in to the holes to the correct depth that allows the 2 magnets to just touch, and the tape prevents the 2 parts from sticking together.
