Grid for the classic Artilux magnetic ball lamp. The original grid is commonly missing on these lamps since it was destroyed by the heat from the bulb. I had none of the grids left, so I designed a replacement based on a picture I found on Internet. READ THIS BEFORE PRINTING: - For this to work, you need to use a LED-bulb, incandescent bulbs will melt the printed grid, just as it did with the original grid. - Try to get a LED-bulb not more than 85 mm long. - Use supports when printing. - There are at least two versions of this lamp. This grid will only fit the one that uses three holes in the reflector to fix the grid.
