Spinning Heart - Keychain

You can add text on top/bottom in slicer for customisable prints or just edit the step/f3d.


Depending on your slicer settings you can get a combination where it does a small blob in the air at layer 12 (2.4mm), it won't fail your print as far as I've tested. 
If you want to “solve” that you can use:

• Classic wall generator or
• Make overhangs printables or
• Inner/Outer/Inner walls printing order or
• etc

• Keychain ring
• Larger radius at the top of the heart for improved strength and first layer
• STEP file for remixes (for other software other than Fusion)
