Duco Black Acetal Copolymer Rod 3/4 Inch Diameter, 12 Inch Length - Rigid Wear-Resistant Machinable Long Acetal Rods - Black Dowels Plastic Bar Stock (Pack of 1)

Is good

Easy to machine, durable. I made some custom spacers from this material.

Just as described. Very rigid and I was able to drill and tap it. Worked great

Nice material. Suited my project very well. Cuts and sands like wood, but melts with high speed. Easy enough to work with. Basically Delrin.
