Birdbone ABS1-5X

7/29/2018 Update: Design name changed from "ABS1" to "ABS1-5X", reflecting true-X layout with 5-inch props. 7/6/2018 Update: Initial GoPro upper and motor guard stiffener files uploaded for use with the ABS1 frame. 7/5/2018 Update: ABS1 initial beta release files now available online. This is the new Birdbone frame, ABS1. It's essentially a Helium, but with a more traditional standoff layout. Options are provided for upper components, or users can design their own (standoff pattern is 34mm x 54mm). A motor guard/stiffener is also included for those who like to push the limits of printing. As implied by its name, ABS is the preferred material for this frame. However, printing ABS frames can be extremely challenging due to warping issues. To overcome these challenges, excellent first-layer adhesion and a warm enclosed chamber are essential. For testing purposes, I'm using NinjaTek ABS for the frame, along with SainSmart TPU (black) or NinjaTek SemiFlex (blue) for other components. This setup is released under an Attribution license, allowing users to remix, share, and even sell these frames. Print Settings: To print the frame, I use NinjaTek ABS as well as any other good-quality ABS material (Hatchbox and Fillamentum are also excellent options). Three-layer shells with 9% hexagonal infill produce a frame weight of approximately 67 grams. A 100C bed temperature is used, along with four or five layers of Elmer's glue stick on glass. To maximize first-layer bonding, I double the extrusion width (line width in Cura) for the first layer. A 5mm brim is also applied. The enclosure is kept at around 50C during printing, and it remains closed throughout the process to prevent temperature fluctuations.
