These stands are made for Moyou, Überchic and Maniology stamping plates and will fit 13 of the size 145 x 95 x 0,8 mm plates and 10 of the size 125 x 65 x 1,6 mm plates.

No supports are needed and the material doesn't really matter.

Do note that the tolerances are tight. If the plates don't fit you can scale each model by about 2-4%.
