Polyformer Tubes Kit — 5× Stainless Steel Tube, 12 mm × 300 mm

The five stainless steel tubes on the Polyformer parts list: 12 mm outside diameter, 1 mm wall, cut to 300 mm. These are the tubes that ship in our full Polyformer kit, sold on their own.

What is included

• 5 × stainless steel tube — 12 mm outside diameter × 1 mm wall × 300 mm long.

Why this kit

• The official Reiten966 Polyformer BOM calls for five pieces of 12 mm × 300 mm tubing or rod, and asks builders not to substitute wooden dowel. This is that line of the BOM in one pack.
• Metric 12 mm. Half-inch tube from a hardware store is 12.7 mm, which is too big for a part printed for 12 mm.
• Goes with the Polyformer Fasteners Kit and the Polyformer Bearings Kit if you are sourcing the build yourself.
