I won first place for this design at GrabCAD's Golden Gear Award Competition on 1/29/2014. Here's a blog on the event.

Our Grabby is standing proud and balanced after spending time in the shop making this commemorative award for you. Grab is quick, or if you wait too long – bad things will happen.
Wow, it looks like Grabby was busy and not only painted the trophy gold, he made a flag out of a drill bit and nut. Take pride in your accomplishments and when you hold this award – know that Grabby ….made a complete mess in the shop and it took hours cleaning it up.
Each of the elements in the design anchors the entire trophy and creates a rigid structure. Designing with 3D printed Sandstone, thin walls and unsupported wires cause issues in the post processing of the final product. Beyond that - shipping impacts any weak areas of the design, developing cracks or broken features.
For example, Grabby’s Waiter tray is attached slightly to his head for additional strength. The weight of the Gears would impact the Arm and break without it. The socket resting on a gear and wooden table – and the Drill Bit, anchor Grabby and provide enough support for the entire 3D printing process (hopefully).
I toyed around with hollowing out Grabby and went against it due to the large exit hole(s) required for unwanted material to escape. Instead, know that Grabby is one solid Robot. When he was hollow…and cold, the cost wasn’t impacted that much versus resizing the entire Award. The base of the award is hollow, since it doesn’t require any exit holes and impacted the cost of the entire product.
A Side Note…
We scanned Grabby on a set of rusty gears that required a lot of time repairing. This was between fixings…. and Grabby instructed us NOT to worry if our CAD files disappear for a few minutes.
At this point, I only have the 3D model ready for printing in standard Sandstone. I’ve never prepared a 3D Model for Color Sandstone and generating the correct files and textures is taking time.
I’ve evaluated the Model at Shapeways.com for any thin walls, or areas that might cause rejection or failure in the process. As a result of this, Grabby’s antenna was enlarged for protection against breakage.
This Product is made of 3D Printed Color Sandstone provided from Shapeways.com. Standing approximately 5.5 Inches tall, the Award is available in Sandstone, Color Sandstone, Strong and Flexible Nylon White, Red, Blue, Pink, Purple and Red.
If this product were purchased today, its cost is estimated at around $85.00 ($100 Maximum). With the shipping coming to about $6.50 – we have a little money to spare ($9). We’ll save that for changes….
