I had to scale the Moon lithophane to 97.5% to fit the Ender-3 bed.  To accomodate the dimension changes in the bayonet lock and the light cord I ordered (https://www.amazon.com/gp/product/B09NW23FXN/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1) I had to design a new base.

SpiralBase.stl and SpiralBaseCap.stl are the two I printed.  If I were to do it again, and hadn't run out of wood filament, I would print the SpiralBase2.stl version because I think it would be less fragile.

I used 0.2 layers and 100% infill (because my wood filament was fragile).  Mileage may vary.

I superglued the two pieces together.

I've uploaded the Fusion model as well.
