This OSAT has been prototyped.

Abstract[edit]

This is a butterfly bicycle handlebars designed to fit 25.4 mm clamp. I designed this to fulfill the request for 3-D printable bicycle handlebars [[1]]. This will contribute towards the goal of making 3-D printed bicycle.

I used press-fit designs from [2]. Basically a circle for outer mating part and 8-sided polygon for the inner mating part. When pressed together, the pointy part of 8-sided polygon will be squished to fit into the outer mating parts.

Bill of Materials[edit]

300 grams of PLA for $6.

The 3D Model can be found here libre3d.com

Tools needed for fabrication of the OSAT[edit]

MOST Delta RepRap or similar RepRap 3-D printer

Technical Specifications and Assembly Instructions[edit]

Print all the A, B, and C part with the flat side on the bottom. After that, just push the part together. You might have to push a little harder to make them fit. The goal is to make them impossible to pull apart after you put them together.

Cost savings[edit]

70 % savings over commercial $20 butterfly handlebars
