While learning about this tool I discovered that you can press the up/down arrow keys and increase/decrease the resolution of the 3d manipulator widget’s snapping grid while dragging the manipulator. Once they were aligned I used Edit/Plane cut to cut the bottom of the egg so that it was wide enough to accept the battery holder cavity. It helps to change the view in Meshmixer to ‘Bottom’. Next I used Edit/ Transform to move battery holder cavtity so that it was centered with the bottom of the egg. Having my own copy in Fusion 360 also allowed me to make small tweaks as needed.īattery holder and egg bottom surfaces aligned So, I printed the LED holder and re-drew it in Fusion 360 measuring it with calipers.
This went ok, but resulted in a lower resolution solid than I liked. My first attempt was to import the STL of the LED holder into Fusion 360 and then convert it into a solid. Since I use Autodesk Fusion 360 for design my next step was to get the LED holder files from Tinkercad to Fusion 360. He has a variety of different egg designs to choose from. After some searching on Thingiverse I came across a great Easter Egg project by Antonin_Nosek. Now that I had the LED/Battery holder I needed a item to install it into. I thought this would be a perfect project for my Circuit Lab group. For this class they created a house using Tinkercad. You can then use a cavity feature to create a cavity in any item to turn it into an LED project. It was a great Instructable class describing how to use Tinkercad to create a coin battery holder that you could use to power an LED.
I signed up for the class and read it through. Since I also have a 3d printer my wife forwarded me this link to 3d printing with circuits. I coach Circuit Lab for Division B (Middle School) Science Olympiad.
