I AM GROOT! We all love Baby Groot at my house, and once I found @dav88's awesome model of him, I knew he'd make a great tap handle. I modified the mesh and inserted a 3/8" UNC thread mesh so it can fit on a standard tap handle bolt.
I recommend a fine resolution to ensure the thread has enough detail for smooth threading onto your faucet's handle/lever screw.
Print it standing up with supports (the chin needs it). Paint the tips of his head with a soft green, paint the eyes with several coats of black nail polish to make them shine.
I'd love to see your final products if you make it!
Doesn't Matter Wood
Use 4+ walls to ensure rigidity in the thread. Print with thread-side down on the print bed.
