Hey, I happened to come across this one randomly while prototyping something different. I thought this was already cool enough to publish.

You need: 1 Heart 14 Connectors 6 Square Pieces 8 Triangle Pieces The tool is optional. I did include an "All" File. You can find all the parts you need on there.

Print Settings: Standard. No supports. You may need to use a brim.

Assembly: I did make a Video how to https://youtu.be/mLEF2qq6oKA. It's simple. First, push the connectors into the Heart. Then push the Square Gears that have a little Square on the bottom on the Square Faces of the Gear. Do the same for the Triangle Gears, but with the Triangle Pieces of the Heart.

Troubleshooting: If your Gears are too loose or to tight watch this Video: https://youtu.be/PWUoJc_Gc84.

If your connectors break, try experimenting with how many walls you print. I usually print 2 walls, but try different amounts to see if it gets better. You can also try to print them with another spool or even another Plastic. PETG works quite well.

Technical Data: The Gear Blob takes, around 100g of Filament and 4,5 hours to print.

The Filament I used in the Pictures is: Green Protopasta Seafoam Green. Blue Protopasta Tidal Turquoise.
