KEY FEATURES

WARNING - RISK OF FIRE

Plastic, especially PLA, can melt and burn. Always use LED type bulbs, never incandescent bulbs.


HOW TO USE THE APP IN 3 EASY STEPS

1- Select lampshade shape and dimensions

 

2- Load and position images

You may load multiple images and position them individually.
For best results and faster print time, use a subject on a white background.
PNG files with transparent background are supported.

PhotoAnim for Windows provides an easy way to isolate subject from background.

Use keyboard arrows to fine adjust position and scale.

 

3- Select a lampshade holder

Top and bottom hole sizes may be adjusted.

 
That's it, enter a file name, and hit "Download" to generate a STL file.
