Doll Dexcom Sensor

thingiverse

My niece is only 7 years old and she has Type I diabetes. She relies on a Dexcom sensor to keep track of her blood sugar levels. When my sister saw a picture of a miniature version of this sensor that someone had made, she asked if I could design something similar for my niece's doll. I was more than happy to take on the challenge. This DIY project consists of two parts: a base and a top. The base is actually a button that can be sewn onto a doll's arm (think American Girl or Elf on the Shelf). The top, which resembles a battery, attaches to the base using magnets. I made sure to include different colored tops so my niece can swap them out as she likes. The magnets used in this project are 2x1mm in size and can be purchased online from Amazon. Here's the link: https://www.amazon.com/gp/product/B07BHF3X86/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 To attach the magnets to the base, I followed these steps: 1. Gather a stack of 10-15 magnets that you can easily hold onto. 2. Apply a small drop of superglue to each hole (not the button holes). 3. Push one magnet into a hole and slide the rest to the side. 4. Repeat step 3 for the other hole, making sure to maintain the same orientation for the stack. To attach the magnets to the top, I used these steps: 1. Gather another stack of 10-15 magnets that you can easily hold onto. 2. Check the polarity with the magnets in the base to ensure they repel each other. 3a. If the top is printed with the holes facing down, you can press the magnets into place without glue. 3b. If the top is printed with the holes facing up, add a small drop of glue to each hole before pressing the magnet in. 4. Push one magnet into a hole and slide the rest to the side. 5. Repeat step 4 for the other hole, making sure to maintain the same orientation for the stack.
