This is a special model i build to promote the littleRP SLA (resin) printer.
the original scale is optimized for this printer (or any SLA printer) . the model is not hollow because the large base prevent it. For a bigger printer (and a bigger scale), you can make it hollow but you will need internal supports.
Also, you can change the scale ( x2 to x2.5 ) to print it on a standard FDM (filament) printer.. (my parameters : 0.15 to 0.2 mm layer, 15% infill , 2 perimeters)
