This is a hand you can use to put your rings on, or just use it as a sculpture.
This hand has a massive bottom, the hand is created with thin walls about 1,2mm thick, so three loops will be used with a 0.4mm-nozzle
I used the open source program "Make Human" to create a man, and cutted the hand out of it. Cutting was done in blender.
Then i created a bottom part. The hand was extruded and scaled with the ALT-S-command in Blender, scaling it to 1,2mm thick walls.
Both parts are exported to the stl-file.
