Made for local printing

Print the part you actually need

A small part customized to your measurements may use only a few grams of filament already on hand. Producing the correct size locally can avoid ordering a bulk pack, shipping it long distance, and being left with parts that never fit or get used.

Use the printer and material available to you, make the quantity required, and adjust the design when the surrounding equipment changes.
