Lower Fixture for a Hanging Lamp Shade - Pineapple Style

Two versions of a part designed to replace a missing lower fixture on a hanging ornamental lamp shade.

The V12 is 10cm in diameter and about 2.5cm in height while the V13 is scaled at 70% approximately. Both are designed to have an M4 trapped nut placed during printing for mounting.

I will be adding a bracket to the part in the form of a large/thick washer which will retain this piece from the other side of the glass shade. Find a customisable washer here: http://www.thingiverse.com/thing:1099603

How I Designed This

Main body was designed in 123D Design.

The Hex nut/bolt was designed using a version of a script I made in OpenSCAD - file can be found: http://www.thingiverse.com/thing:1103895
