SCP Challenge Coin: MTF Eta-77

prusaprinters

<p>I recently came across the concept of the <a href="https://en.wikipedia.org/wiki/Challenge_coin">challenge coin</a> and thought it would be cool to create some for the SCP Foundation's Mobile Task Forces.</p><p>This coin is for members of MTF Eta-77 ("Spheres Within Spheres"). SCP logo by Far2; Eta-77 logo by EstrellaYoshte.</p><p>Some notes on the design:</p><ul><li>The coin is 45 mm (just over 1.75") in diameter, providing a balance between reasonable coin size and print resolution, and 2 mm in thickness.</li><li>The coin has the SCP logo on one side and the MTF logo on the other. I would recommend printing with the SCP side down, as this minimizes the amount of printing over thin air involved. Depending on the quality of your filament, you may experience some light stringing between features, but I've found that an Xacto takes care of that fairly easily.</li><li>The recommended parameters (as included in the gcode file) are 0.10 mm layer height, no supports, and 15% infill. Additionally, there are two color changes included- to get the results in the picture, I started with black for the first 0.5 mm, switched to white for the middle 1.0 mm, and switched back to black for the last 0.5 mm.</li></ul><p>All currently available coins can be found <a href="https://www.printables.com/social/186038-suaz0/collections/241273">here</a>; let me know if there are other MTFs whose coins you'd like to see!</p>
