Star Trek Badges

I'm just a huge Star Trek fan, and I tried creating these badges all by myself using some pictures and photos I found online to model them. To attach the badges to your shirt, you'll need to use the following magnets: 4 disc magnets, each 4 x 1 mm in size. You can find these on Amazon at this link: https://www.amazon.de/Unbekannt-100-Neodym-Micromagnete-Zylinder/dp/B00CLPZYF8/ref=sr_1_3?s=officeproduct&ie=UTF8&qid=1502533505&sr=1-3&keywords=magnet+4x1 You'll also need 1 sew-in magnet for the shirt, available on Amazon at this link: https://www.amazon.de/Scheibenmagnete-Einn%C3%A4hen-quadratischer-PVC-H%C3%BClle-Haftkraft/dp/B072PRHJBL/ref=sr_1_1?s=kitchen&ie=UTF8&qid=1502533698&sr=1-1&keywords=magnete+zum+einn%C3%A4hen To integrate the disc magnets into your print, generate the g-code and check the first layer level that closes the holes for the magnets. Open the g-code file with a text editor and search for the first "Z" layer level. Write one line before the text: "M600 E0 L0 ;" and save the file. If you're using a resolution of 0.1 mm, the first closing layer will be 1.4 mm. Look for the first Z1.4 in the g-code and write one line thereover M600 E0 L0 ; (don't forget the dot comma). The command M600 stands for filament change pause. It should look like this: G1 X123.204 Y103.192 F7200.000 ; M600 E0 L0 ; G1 Z1.400 F7200.000 ; If the last layer before closing the holes is finished, the printer will pause. Now, put the magnets into the holes and make sure to have identical pole direction on all magnets! Also, keep in mind the pole of the counter magnet on your shirt. When you push a button to continue the print, be aware that the printer will extrude some filament before printing. Make sure no filament gets stuck on the extruder. After printing, you can prime and paint the badges. I'm printing with a Prusa Mk2 and haven't had any problems with the magnets on the print bed. Just a note: if you have a pacemaker, be careful not to use magnets on your chest. Instead, you can print the normal model (without magnets) and use double-sided tape.
