I created this pendant of 55x55x3 mm and 0.70 mm bottom from a clipart found on pinterest.com
It's the hollow version of my Celtic heart 3
The hole ...to pass the chain is 4 mm inside diameter.
for those who know how to change the filament during printing and want an object in 2 colours, replace the filament as soon as Z > 0.70
