Record Adapter / Schallplattenadapter - Cupcake

This is my record adapter in shape of a cupcake.
There are 3 different versions: a standard, a ball at the top and a cube at the top.

Update: Reworked the modell because the given dimensions in the contest are wrong. They say the middle axis is 0,25" which is 6,35 mm. In fact the axis are 9/32" which is 7,14375mm so i made them 7,4mm to make them fit nicely.
