Hi and thank You for visiting my blog.

This blog is about my professional work, projects I have been working on, and some funny and interesting things about mechanical engineers. On these pages You can find some of my projects, as I work for army and I am not able to enclose all projects I have been working on.

My most recent designs You can find in posts below.

For more interesting projects You can follow labels, such as:
- aircraft engine blades

- aircraft parts

- wind tunnel models


You can download some of my models, posts with files for download are labeled free model download.

or You can go to INDEX page and search through list of all projects on this blog.

Info about me is on ABOUT ME page, where You can see my professional CV and some info about my skills and professional knowledge.

For all questions about my work, projects, blog or job offers contact me over e-mail or Skype. E-mail form and Skype Add Me link are on CONTACT ME page.

For those who are interested in learning new stuff about Siemens NX program I made NX TUTORIALS page, where I will post some tips and tricks about how to use NX more efficiently.

Zippo lighter, 3D model

designed in Siemens NX6

Just a Zippo lighter CAD model I made today in some free time. I am not sure that inside parts are in real dimensions as I measured images of zippo lighters in photoshop to get most of dimensions, but it can be edited. I am trying to make render of flames so I can make more images, but it is hard to do in NX. If there is anybody who know how to set up material in NX to look like flames, please help me!

About Zippo lighter: besides having gained popularity as “windproof” lighters, Zippo lighters are able to stay lit in harsh weather, due to the design of the windscreen and adequate rate of fuel delivery. As such, until recently they were highly popular with backpackers and within the military.

Constuction of zippo lighter: the cases of Zippo lighters are typically made of metal and are rectangular with a hinged top. On most models, the top of the case is slightly curved.
Inside the case are the works of the lighter: the spring-toggle lever that keeps the top closed, the wick, windscreen chimney, thumbwheel, and flint, all of which are mounted on an open-bottom metal box that is slightly smaller than the bottom of the outer case, and into which it slips snugly.
The hollow part of the interior box encloses a rayon batt which is in contact with the wick. The fuel, light petroleum distillate or synthetic isoparaffinic hydrocarbon (commonly referred to as lighter fluid or naphtha), is poured into the batt, which traps it. It also contains a tube that holds a short, cylindrical flint. The tube has an interior spring and exterior cap-screw that keeps the flint in constant contact with the exterior thumb-wheel. Spinning this rough-surfaced wheel against flint results in a spark that ignites the fluid in the wick. 

old version with "cam" that is not shaped to fully close the lighter

new version with new "cam" that look and work (in CAD of course) like real lighter

After few hours of trying this is first "flame" result:
