Story

The Project

This printed table base (for a 24 inch glass table top) uses a ghost for a Halloween theme. My wife, Annelle, created the ghost in clay and I scanned it with the Makerbot 3d scanner, then modified the scan using Tinkercad.

This takes 1.2 kilograms of filament and requires around 50 hours of print time.

My inspiration came from art pieces by www.Mousarris.com. If you want their beautiful and well designed table (Rocket Coffee Table), it will cost around five thousand Euros--which puts a roll of filament and a few hours of print time in perspective.

The 3d print files for Ghosty Table can be found here.

Directions

Print three of each piece and stack them like this:

If you don't want to fool with electronics, it will look like this:

Assemble the electronics according to the schematic and it will look like this:

Two of the ghost heads do not have ping transducers and their eyes shine in the dark.

Enjoy your Ghosty Table.
