A 3D printed Christmas tree topper. I created this after years of searching for one I actually liked.
For best results, print this star in PET / PETG... / T-Glase; it has been tested for many hours with this material and transmits the light beautifully. Clear ABS should work also. PLA has not been tested and it is unknown if it will withstand the heat generated by the LEDs. It may work, but use at your own risk. The two halves are a tight fit. You must have your extrusion factor calibrated nearly perfectly. Assembly instructions included for download below.
