When I was a little boy I always painted eggs with my parents on Easter. To share this fond memory I decided to create my own version of an egg painting station. It allows you to place an egg (between 45mm & 65mm long) and rotate it smoothly with the bottom or top red pins.

It also uses 3D printed springs to hold the egg! So no need for any extra parts besides PLA. I suggest enabling Support for some of the parts but I tried minimizing it with the holes and orientations. Also, you don't need any Glue to put this together, the ‘Arch’ sits firmly on the base and the seperate (and interchangeable) ‘Paint Tray’ has extruded bits to make sure it stays in it's place.

The .3MF file contains 2 plates, one for each colour (I chose white for all the parts except the pins, those I printed in red). If you want to print it all in 1 colour just move the pins over to plate 1. Plate 1 also has both 2x ‘normal springs’ ánd the 2x ‘smaller springs’, I suggest printing them all so you can swap them if needed. (EDIT: Consider printing both pins 2x as some users have experienced fragility issues)

Short instructions on how to assemble;

• Place the base-plate
• Slide the paint tray over it until it locks in place
• Add the Arch
• Combine each pin with a desired ‘spring’ 
  • Place the short pin in the bottom part of the arch 
  • Add the longer pin (with spring) to the upper part of the arch 
     

Use the extruded areas on the paint tray for your favorite paint colours!
