DeathTrooper (3D Printed) Storm Trooper, IWI Tavor, and Tannerite

For this project, I had a chance to collaborate a bit with my brother and his buddies at their YouTube channel, How2Man. 

I have an IWI SAR Tavor, which is a really fun 5.56 bullpup rifle, and thought it would be great to showcase this weapon for this collaboration video, and use it to destroy a 3D printed object using Tannerite.



I found an excellent STL of a DeathTrooper online, which is basically a Storm Trooper helmet that shows a bit of battle damange, and the skull inside.  I increased the size of the print to better allow for us to fill it with around 2lbs of Tannerite.



The entire print took around 36 hours to complete, and once done looked absolutely AWESOME!  I was almost sad that we were going to blow it up... almost.

I added a tad of acrylic paint to make the skull more noticeable. Also drilled a small hole in the bottom of the helmet so we could pour tannerite into the hollow portion.



Here is a short video showing the print and a 3D Render of the object.

And here is a longer video showing the process we went through to fill the helmet and detonate it using the Tavor. There is some cool slow-motion in addition from some drone video from my 3DR Solo. Enjoy!

Solar Eclipse Pics & Celestron Telescope Filter (3D Printed)

The August Solar Eclipse was an amazing event. Luckily for us, we were only a short 3 hours away from Totality.

In addition to watching the eclipse with my family, I wanted to use my telescope to better see the the event. I have a Celestron NexStar 127STL, which is roughly a 5in Maksutov-Cassegrain. I was surprised after looking on Amazon and B&H Photo, in the lack of available slide-on filters for this size of telescope. So I set off to design my own.

The most important part of this “make” is the ability to block out the harsh brightness of the sun, so I grabbed an appropriate sized solar film. I found a 6in x 6in film on Amazon for around $15.

With that selected, I set out on the slide on filter design. It consists of 2 parts.

• Primary cap to slide over end of telescope and hold the film
• Secondary ring to hold film against the larger cap 

Pretty simple to create after measuring the telescope and creating the initial design in SketchUp. I also chose to add some clips to the outer cap to keep the inner ring snug against the cap, therefore keeping the film in place.

With the design completed I printed the two parts, and cut the film to fit inside the outer cap. The print came out great, and for perfectly over the 127STL.

Problem is, this was printed in PLA and I was worried that the hour leading up to the eclipse, would be too hot for the PLA to handle. Reprinted both parts in ABS.

With the final print completed, we drove to St Anthony, ID and set up camp. We were part of a sizeable viewing party, And I began taking photos with my camera about an hour before the eclipse actually started, and let people come up and see the sun in all it's filtered glory in the telescope. Sun Spots were easily visible.

The eclipse began, and a hushed silence and twilight darkness was ushered in as Totality approached. Once we hit full totally, I pulled the filter off, and was a amazed at the detail that was visible,especially the colorful corona  around the eclipsed sun. In person it was amazing, but I wasn't able to really capture it with my DSLR or through the telescope with my phone. I decided to stop messing with it, and just enjoy Totality with my family.

After the event, we drove home and I began to sort through the photos. After minimal editing, I had a pretty good “Timelapse” of the eclipse process.

Here is a modified pictures with the key eclipse phases placed next to each other.

Overall the print worked perfectly, and I will hold onto it for future Sun viewing. Also want to invest in a better camera mount for better pictures, and will be sure to post an update once I have something to show.

Not really eclipse related, but I was able to get some pretty good long exposure shots the night before.

Thanks for stopping by!
