Yet Another Keyblade #3DPrinting #KingdomHearts

Does the world need another Keyblade? This Keyblade is designed to be an easy-to-build kit with parts that screw fit together. No support material is required! 3D print and build your own Kingdom Key!

Use a brim where necessary. First, print out the tester-tube.stl twice and see how well they screw together – Adjust slice settings as necessary.

Need to change the diameter of the screw? How about using different heat set inserts? The parts are setup with user parameters, so it’s easy to change a value and automatically update the features in CAD. Tolerances use a “gap” to give clearance between mating surfaces – slight adjustments make big differences.

The fusion 360 source file is included and features original sketches and feature timeline along with easily editable user parameters. The parts can further be separated into small pieces for fitting on printers with smaller build volumes. Note: STEP file is included for other 3D surface modeling programs such as Onshape, Solidworks and Rhino.

The blade is comprised of seven parts. The collar joins the tubing to the handle. The pipe extension is printed twice to lengthen the tubing. The key wards slide into the v-slot on the pipe-key.stl part. The pipe-top-cap.stl part is designed to snap fit and locks on top.

The handle is comprised of six individual pieces. The cross guard requires M3 screws and heat set inserts. The end cap and connector parts are keyed and snap fit into registrations in the cross guard.

Knurling Textures
The grip in the handle features knurling texture that wraps around the cylinder. This design technique is achieved using the coil and circular pattern features in Fusion 360. Watch my Layer by Layer tutorial below for a deep dive on how to apply knurling to your parts.

Screw Threaded Parts
Most of the tubing pieces feature screw-threaded ends allowing the parts to simply screw together. This uses the coil feature from Fusion 360 to create threads with custom size, pitch and height. Watch my Layer by Layer tutorial below for a deep dive on how to design parts with these features.

Timelapse Tuesday Playlist:

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here:
