Moon Buttons

My wife is quite the seamstress, and is making me a space themed button down shirt. I thought we could collaborate, and I would design the buttons for the shirt. I present to you, my moon buttons made with a 3mm rim for a subtle look, 1.5mm rim for a classy look, and rimless for a full view of the moon! These are designed to be a 20mm button, but seem to scale nicely.  

These are best printed with a 4mm or 5mm nozzle, set to 0.20mm resolution. Slowing print speed and nozzle temperature also helps achieve better detail.

Designed in Tinkercad.
