Pen with Whistle and Secret storage

prusaprinters

I present to you my own design of a multifunctional Melody whistle. It's not just for whistling, you can also use it to write, it has integrated rubber eraser for fixing text and a hidden compartment for small secrets or banknotes . It looks cool when you blow into your pen while paying for a beer with money from secret compartment ;-) The whistle design is inspired by the simple ones we used to make as kids from wooden sticks. You need a bit of practice to make it sound good, just like any other instrument to not produce false tones. You can whistle with roller refill itself or with designed refill equivalent (3D model included). Infinity pencil last 100-150x more than normal graphite pencil. You have to purchase on the internet for price like 15cents per piece. Link to Aliexpress is below or on my cult page.Also you can download stylish pen cover with integrated rubber eraser for text correction. Link to rubber also available below on my cults3d page. Instead of normal refill (best is standard ceramic roller refill for price under 1EUR) here is also link to purchase gel roller erasable refills. Pls check my other genuine designs on my page:https://cults3d.com/en/users/vavrenaeu/creations (here is also animated gifs which do not work here on Printables)https://www.printables.com/cs/@vavrenaeu_443350/modelsHOW I MADE IT: I based the whistle's outer shape on the pens that I make from wood and epoxy (check them out on my website: https://vavrena.eu/). 3D models of my pens is created from scratch by using freeCAD. By changing the roller pen with "infinity pencil" tip, I made more room for new features. The infinity pencil has then like exchangeable extensions: a two-tone strong loud whistle, waterproof storage for medication (fits about 10 tictacs), and now I'm working on a stylus version for tablets and mobile devices. The latest version has a fancy mesh design that will also allow for the integration of the Melody whistle in the future. PRINTING: All parts to be printed as is, straight on the build plate. No any supports, sanding or other postprocessing is needed. I use SLA but it is also tested on FDM printers. Orientation as seen on very last picture (three orange parts as an example). Layer thicknes could be 0,1mm, but better is 0,05 as threads is more smooth. Spare parts/refills:Super cool Eternity pencil tips you can buy e.g. herehttps://www.aliexpress.com/item/1005003510792778.htmlReplaceable erasers (internal and external) herehttps://www.aliexpress.com/item/1005003620419200.htmlGel erasable rollers (standard length ca 110-111mm) e.g. here https://www.aliexpress.com/item/1005004037516851.html
