These are some additions I made to @3DPRINTINGWORLD ‘s awesome lightsaber. I love to cosplay and needed these items to complete the saber for a prop I so I can wear it at a con.
The end cap is the same as his, but two holes have been added. One for the Key Ring and one as an air hole. I find the blades extend much better if there is an air inlet to relieve air pressure.
The Key Ring has a slight break in one side so you can slide it in the hole. Then superglue the two ends.
The cap has a thumb tab to help you get the cap off and inside the cap are small tabs that latch to hold the cap on. This was necessary addition to keep the blade in the hilt while wearing the saber on your belt. I printed it at 100% and had no trouble popping it on and off. Depending on how you printed your saber, you may have to increase/decrease the size in your slicer.
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!
