Because this is a massive weapon and most common printers are limited to 8″x 8″ x 8″ , the entirety of this prop has been processed to fit in within this build area.
While ABS is a very strong material, at this scale I would not trust it to hold up to the abuses of a convention on it’s own. To give a little more strength to the axe .25″ sockets were run through the major sections of the head in order to hold delrin, acrylic, or wood pins . These pins assist in part alignment as well as greatly increased the props ability to withstand shearing force across the sections.
The axe head surface can be processed by using a combination of acetone chemical smoothing and various grits of sandpaper. Depending on how nicely your prints come out I’d recommend starting at 150 grit and working your way up to 320 before smoothing and unifying the surface with a rag or paper towel wet with acetone. Make sure you wear proper protective equipment (gloves, goggles, shop apron) when working with chemicals – 3d printing is fun but not at the cost of your health!
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!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
Have an amazing project to share? Join the SHOW-AND-TELL every Wednesday night at 7:30pm ET on Google+ Hangouts.
