I made this box for a holiday gift exchange, and also to learn how to use Fusion 360. It is a cylindrical box consisting of a screw-on lid and a logo of The Flash on top of the lid. Lacking access to red filament, I instead printed the box in blue and covered it in red acrylic paint. I was also able to use the paint as an adhesive by pressing the logo into it before it dried fully.
The logo can be lasercut with the provided DXF file, or it can be 3D printed from the STL file. I've also included an SVG from which the DXF was produced.
I set the layer height to 0.3mm in order to shorten the print time.
3D Printable Threads
A neat feature in Fusion 360 is the thread generator, which not only performs a helical sweep automatically, but also has preset sizes for various measurement standards. In order to make the threads 3D printable, the edges of the threads have to be rounded off a little bit (as in this helpful video) so that the parts can be screwed together without too much friction.
I created the threads with the following dimensions:
- ISO Metric, right-handed
- Pushed edges in by 0.5mm
- Fillet edges with r = 1mm
The threads came out perfectly on the first print, making the box quite satisfying to screw together!
