This stand will hold a flat bottomed model off the surface so the underside can also be finished. Printed in HIPS should allow for the use with the acetone vapor technique, but my use is with epoxy coatings.I printed in HIPS so that I could try it with varying finishing techniques. Scale to fit your model's base. The prongs are long so they can be trimmed if they happen to stick to the model during finishing and allow for it to be reused.
