This is my version of a Jedi Training Remote. It is as accurate as I could get while trying to make sure it is printable. It comes in two main halves and is hollow allowing for electronics to be added. The wheel hubs insert into the main halves separately which allows you to put the translucent printed windows behind them and also behind the other hatches to diffuse whatever light you decide to insert in this.
The two halves are designed to snap together. The tolerances are very tight so you may need to file the connecting points to get it to assemble properly. I also designed this to work with a magnetic levitation unit that can be found here...
You can glue the Mag Lev puck inside the bottom sphere in the indent I provided or just balance it on the puck. The cover is designed to fit this particular mag lev unit since it was very affordable.
Please note: I molded the Jedi Training Remote and then cast it in rigid foam from Smooth-On to make it lighter and easier to levitate. You can levitate a printed version but may need to upgrade to a stronger levitation unit. The same style unit can be purchased at different lifting weights. The one shown lifts about a pound.
