This model is a simple model holder for painting minis and busts. With the flat top I usually use a dab or two of hot glue to hold my models down, it seems to be more reliable than blue tack. The grip is parametrically driven so you can open the fusion file and play with the parameters and adjust the design as needed. 

Note, I designed this specifically for larger models, because that's what I normally paint. You could also play with the parameters in the f3d file to adjust the holder to whatever size models your painting.

P.S. Models shows are made by Fotis Mint
