Coffee piston stamper 88mm

For 88mm pistons

Its in 2 parts so 2 different colors can be used

For other sizes scale as following:
size% = 100 / 88 * {target diameter}

So for say a 70mm piston: 100/88*70 = 79.5%

Prints without support
PETG is a good material

Print with thick walls and bottom so it does not bend

I used 1.6mm solid bottom and 4 walls
