Night Light Box from Lithophane
(no engineering required)
I decided that it was finally time to get a night light for my sons room. But since we make 3d printers, I couldn't just install any ole' standard night light! It has to be something really cool. So I designed this night light, no engineering required! You can make this fun project with your kids or students with free software and little effort.
Here are the steps:
You can use any photo software to flip the jpeg...In this case I used "Paint" which comes with windows for free! I flipped the image.
Next I used this awesome slicing software by Airwolf 3D, called APEX. This is where the magic happens. Under the file menu you will find a little known fantastic option "Load image file."
APEX will prompt you for some settings. Set the height at 10 mm, this is how thick the photo will print at the highest points and set the base height at 0.7 mm (this is the lowest and thinnest parts). The dept should be at least 85 mm, so that printed image is tall enough to cover the top of your light bulb, APEX will change the width to the default ratio. Leave the other settings as they are.
APEX will then convert your image into a 3D printable model, or as some like to call it, a "lithophane"
You are now ready to export the lithophane model for editing in your preferred CAD program. Save your model as an "STL file.
Be sure to add ".STL" under the file name prompt.
Next Import your lithophane model into a CAD editing software. I used TinkerCad to draw this, because it is incredibly easy - and FREE!
Next, connect the lithophane model to this box cover and voila you have designed a custom night light!
Allows the buyer to print up to 100 copies for home use only. Purchasers cannot distribute or sell the printed items and they cannot distribute or sell the digital design. If they wish to print more than 100 copies they must buy multiple licenses.
Allows the buyer to print up to 1000 copies for business distribution purposes. They cannot sell the printed items and cannot distribute or sell the digital design. If they wish to print more than 1000 copies they will have to buy multiple licenses. Ex: A small business wants to print and give away iPhone cases as promotional items.
Allows the buyer to print up to 2500 copies of this sweet design and to sell those prints for whatever price their heart desires. They do NOT have the right to distribute or sell the digital design. If they wish to print and sell more than 2500 copies they will have to buy multiple licenses.
The only other setting you will want to modify is the FILL DENSITY to "100%". For those 3der's out there that want to geek out on the specifics 3D printer settings for this polycarbonate part:
layer height:(mm) = .2
shell thickness = .5
fill density = 100%
printing temp = 285 C
bed temp = 140 C
initial layer thickness = .4
Make sure to print it with 100% infill and use WolfBite Mega to ensure a nice smooth flat part!
