Shape your own plastic parts

Recently I ran across ShapeLock, which is a plastic that can be shaped and formed at home. The company bills it as a "Ultra High Molecular Weight Low Temperature Thermoplastic". ShapeLock starts out as small plastic beads that when heated above 150 degrees melt and become malleable. Once a shape is formed and the plastic cools it is rigid and strong.

The cooled plastic is machinable and paintable, and looks like it will be perfect for creating custom plastic parts for a variety of uses. The material is also infinitely reusable, as it can be melted down and reshaped easily.

I purchased a 500 gram tub for $24.95 that I think will be sufficient to create dozens of small parts. The company also offers a free one ounce sample (plus shipping) so you can try before you buy. I have been very pleased with ShapeLock.
