3D Printing an Eskrima Stick

It feels natural, but it is not quite strong enough to take a beating.

For this entry, I attempted to build an Eskrima stick using a 3D printer.  Personally, I love rattan sticks, but it is not very easy to put sensors and other instruments in a traditional eskrima stick, so I decided to give this a shot.

The designs and instructions are all uploaded to the thingverse for anyone who wants to print their own or improve on the design.

It turns out ABS plastic is not strong enough to match rattan.  In order to get the right weight, I had to use a 30% infill, which means the inside of the stick is filled with a honeycomb pattern.  This is strong, but still no match for a traditional eskrima stick, and mine broke after only a few full-force strikes to a punching bag.

Maybe I'll just put some duct tape on it.

The stick felt great, and it is perfect for practicing forms or playing around with, but it is not suitable for sparring yet.  In the future I may try different designs, different materials, or perhaps some cyborg of rattan and plastic that can house some electronics.
