Chainmail - Customizable Tool

What is Chainmail - Customizable Tool?

Chainmail - Customizable Tool is a free MakerWorld customizer that generates sheets of chainmail with every ring already linked, so the print comes off the bed as flexible mail with nothing to assemble. The rings are fixed at 1 mm thick with a 6 mm radius. You choose how many rows, columns and layers you want, and the stacked layers print joined to each other, so the unfolded sheet can be larger than your build plate. That helps on small printers like the A1 mini.

The ready-made print profile is only a small 12 g swatch, so bigger pieces go through the Customize button. Support walls are built into the generated file. Many makers settle on 20 rows, 19 columns and 3 layers per plate, and commenters advise an odd column count because even counts have pushed rings into the supports. For sheets bigger than the form allows, the designer suggests editing the .scad file, and a separate repair link model from the same designer joins panels or replaces broken rings.

Commenters get the best results with regular PLA. Silk PLA tends to come out brittle, and PETG works for some people but not others. Since April 2025 the model has been customized more than 14,700 times. It suits cosplayers and costume makers who want armor panels or a fabric-like print.
