Notes:

the idea was from MakeAlot .
i took notes of all the tips from the comments that various people wrote on MakeAlot,s source page and used all that info to put the print time down to 18 hrs 40 mins ..from 30 +hrs to create a dolphin scene lithophane lampshade for my mother who absolutely loves dolphins !!! she was overjoyed when i turned on the lamp !! ;)

P.S. I did make the shell 4mm deep as the thinner shell let to much light through as i wanted it to look like an underwater scene which had some really dark shadows .. which made it look better , i also used a 5 mm brim just in case the footprint was not enough to stick to the bed .

i was quite impressed with the result thanks for the idea MakeAlot !!

ive now uploaded a short vid showing the whole shade ..

no rafts just used a 5 line rim for more footprint to aid sticking to bed

UPDATE:- ive now uploaded the (repaired files) so no need to use netfab ect ;)

How I Designed This

step by step instruction using my settings for this shade,

i measured the circumference of the original shade and made a template in photoshop of that size then found and downloaded the pic from google and used the photoshop template to crop the image in an area that i could easily merge and stitch together leaving no join .. and then de-saturated the colours in the pic ,to turn it black and white , then a little bit more contrast added to bring out whites a bit more and shadows darker .. then upload the cropped image to http://3dp.rocks/lithophane/ , in the 3d rocks software go to settings, , then in model settings adjust the size settings to whatever is good for you ,i chose 400mm to see detail (as you can adjust scale in slicer too) whilst still in the model settings my settings were as follows ..thickness=3mm,Border was =0mm (as i wanted no appearance of join in final model !!) ,Thinnest layer =0.8mm, Vectors per pixel=4mm,Base stand depth =0 ,then in the main window choose ..Outer curve not the solid cylinder and slide the curve all the way to 360!! . ... you now have all the info i had to make your very own 3D lithophane Lampshade

another thing i did was to incorporate a black line top and bottom of main image before uploading to 3dRocks site this was to ensure of a border top and bottom of printed shade (as black would give a thicker line top and bottom for stability)

part of actual image taken from internet after cropping and adding black lines top and bottom

same image as above but with 0=saturation and high contrast added

now added a short vid showing some of the steps i took this vid was originally made for a person who sent me a private message asking for some tips .. to explain the steps would have taken me ages to type so i made this vid ;) https://youtu.be/L444f6NXX08
