Litho Keychain

Hi Friends, This i a little keychain with a lithophane.

The first part is to get the lithophane Go to https://tool.itslitho.com/ or your favourite site and load the picture of your choice up. Use - shape circle - diameter 4cm - min thick 0,8mm - max thick 3,2mm - frame thickness 2,5mm - frame depth 3,4mm - leave the rest by default - you can increase the quality if you want

download the litho and load it in your slicer. I have an example for you as .stl file ( its my lovely dog Lucky:-) ).

Second part is to print the lithophane - Its important to print it with no infill. Just increase the number of perimeters/walls to get a solid body ( I use 10 ) - I use the support on build plate only function and a brim and if you dont print too fast you should have no problems - I printed with 0,1mm layerheight

The last part is to print the frame an get the two parts together I printed the frame with the same settings as the litho - I recommend to disable the thick bridges function - You need a printpause at layer 41 (by layerheight 0,1mm ; firstlayerheight 0,28mm)

If the print is paused, put the litho in the frame. Dont push too hard, it should have only a little friction with the frame so it dont move. The Top of both parts should now be even. Then resume the print.

I printed the frame with Silk Pla+ to get a metallic touch.

Thats all :) I hope you enjoy this little project.
