SpaceX Falcon Heavy 3D Printed

Around a year ago, after SpaceX Falcon Heavy first test flight,  I found this amazing 3d model for Falcon 9 and Falcon Heavy on Thingiverse from the user chemteacher628. I’ve decided to print it myself, so I downloaded the parts, uploaded them to Tinkercad to assemble the model virtually before printing it, to check if everything was ok. While I was checking it, I’ve decided to make a few changes. Now that Falcon Heavy has taken off again last week, I thought it was a good time to share the modifications I’ve done.

Playing with nixies: Yet another Nixie Clock

Nixie tubes are electronic devices for displaying numerals or other information, such symbols or letters. They work under the  principle called Glow Discharge. Basically, they are tubes filled with a low-pressure mix of gasses and two (or more) metal electrodes. When a voltage is applied to two of this electrodes, and such voltage exceeds a certain value called the striking voltage, the gas in the tube ionizes, becoming a plasma, and begins conducting electricity, causing it to glow with a colored light (depending on the gas filling the tube, for tubes with neon this color is red-orange).
