This is a remix of Easter Egg Decorating Lathe by gobo333
https://www.thingiverse.com/thing:4805100

The basic changes here are:
Got rid of the crank because it didn't really work and isn't necessary
Added alignment marks to the risers and the egg shaft to help rotate the egg accurately
Added a table to slide a pencil across so that you can make straight lines
Made the inner diameter of the shaft lock and the crank slightly smaller for a tighter fit
I included the crank file here although I decided not to use it

You will need 3 M3x5mm hex socket flat head screws and 2 M3x5mm hex socket head cap screws and 1 rubber band.

The base is in 2 sections so you can print them at the best orientation for each part.
You can fine tune the height of the columns in your slicer if desired.
Parts (except for the sliding riser) are meant to have a tight fit.
All work done with Tinkercad. The project is here:

I used baseplate supports on the columns so they would print nicely.
