Yesterday the delivery containing the new PLA-plastic and the spare thermistors arrived. I fixed the printer and after flushing out the remaining ABS I tried printing some stuff. Without any calibration, just drastically lowered the speed. I used Slic3r┬áto convert the .stl file to gcode and pronterface for printing. Of course, there’s a timelapse. Just watch. There’s a realtime-timer at the bottom left.
Finally some pics of the parts. It’s not perfect but still a better first try than some of what I’ve seen on youtube.
Next up: Calibration!
The heart is made out of some metal that I got from an old hard disk case. I created two equal halves by first sawing out the rough shape from both metal pieces and then sticking them together so I was able to perform the fine working steps on both pieces equally. Then I sawed out the notches for the two magnets. They had to fit really tight because they would be the fastener of the bracelet.
Once the rough metalwork was done I started with the wires. I used phone wire because it is soft and colourful. Once the insulation was removed from the ends of the wires, they could be soldered to the heart pieces by using a hot air gun to heat up the metal and then just the good old soldering iron. The critical point is the length of the wires. Because of the shape of the heart the wires are of varying length. Also, approximating the wrist of my girlfriend was quite hard because every millimeter matters, but I was lucky.
Lastly, I used hot glue to glue the magnets to the heart pieces and to seal off the soldered area from the skin. The hot glue also makes the back side of the heart pieces nice and flat and soft so it is comfortable to wear.
I hope I could give you some Ideas on how to do this on your own. If you have any Ideas and want me to try to put them into practice, tell me! I’d love to!
Meanwhile, it is broken and I threw it away because I don’t want to be reminded of a girfriend who betrayed me and lied to me.
