Put the inner part in the outer part, place it on a table and try to seperate them without lifting, tipping or tools. Let friends, family and relatives try it too!
Printsettings
Outer part:
100% infill (feels more valuable and does not slip so easily)
Inner part:
No bottom layers
2 Perimeters
5% lightning infill (to keep it as light as possible)
I used dual color filament because it looks so cool :)
Post processing
you may need to use the sandpaper to sand away any small excess on the inside of the outer part
I am happy about a like and the posting of a make!
