Solar System Lithophane Planet Lamp Collection - ⌀25mm

Introduction

This model is part of my Solar System Lithophane Lamp Series. As of now, all planets and several moons of the solar system are available as lithophane lamps in five different sizes: ⌀295mm, ⌀205mm, ⌀150mm, ⌀75mm, ⌀25mm (this upload).

All lamps of this upload are available in two versions: a regular version, where the panet/moons north pole faces upwards and a version rotated by 180° where the south pole faces upwards. The latter have the prefix _USD_ (for UpSide Down). Depicted below are only the upside down versions.

If you like my work, please consider supporting me. Your support will help me to make more models available for free. https://ko-fi.com/fritzpeppone. If you like to use my models commercially, please obtain a commercial license by joining my club. The commercial license includes all of my models except those that are based on the intellectual property of others (e.g. the GTA V map lamps) or remixes (e.g. the Death Star or Phobos lamps).

Requirements

All Lamps have a size of ~ 25mm x 25mm x 22,5mm. They should print fine on any modern FDM printer. You will only need around 3-5g of Filament (preferably PLA or PLA+) per lamp.

The lamps are mounted to their base with a M12x1 metric thread. I provide several different base options that all use the same thread but are intended for different light sources. Choose the lamp of your liking and match it with the lamp base that matches your choice of light source. Currently, the lamps can be illuminated by generic fairy lights and by battery-powered magnetic switch LED PCBs.

Print Settings

There are only a few settings you should tweak in the slicer to print the lamps. 

• Print in PLA or PLA+

• Recommended layer height: 0.10mm or smaller

• Use the Arachne Perimeter Generator for more precise printing with better details

• If you use Arachne, set the minimum line width to 75% to avoid holes!

• Set wall count to 7-8 to obtain a solid lamp

• for Saturn, activate extra perimeters on overhangs

• Set number of top layers to 10

• Set seam position to aligned

• If necessary, activate Brim (Outer Brim Only) and set the Brim width to 5 mm

• No Support required! The lamps print perfectly fine without support. All lamp bases come with in-built snap off supports (where required).

Excellent bed adhesion is critical! 
Due to the small footprint of the lamps, they may come off the bed easily. I've had bed adhesion issues on 1 in 10 prints. Clean your bed properly, make sure that your z-offset is spot on and consider using adhesion helpers such as 3DLAC. You may also use a brim but be aware that it may leave artifacts on your lamps.

Be aware, that slicing may take a very long time. The STL files can take up to 10 min. to slice. 

For Bambu Studio users: Bambu Studio seems to struggle with the Arachne Perimeter Generator. If you are unable to slice a lamp with Arachne, use the Classic Perimeter Generator.

This is not a SpeedBoatRace print! Use conservative print speed settings to avoid artefacts! It's totally fine if your print takes several hours to finish.

Filament

Filament matters. A lot! Depending on your filament choice, your lamp may have more or less contrast or a warmer or cooler color temperature. The picture below illustrates this:

All of the four Panels above were printed with different white PLA/PLA+ filaments but illuminated with the same 1W LED bulb. 

You may test your filament by printing the Solar System Lithophane Calibration Panel. However, since printing the planets will only consume 3-5g of filament per planet/moon, I recommend to directly print the planet lamps and see how they turn out.

My personal favourite filament and the one I used for all lamps in my photos is Filament PM PLA+ White.

Planet Lamps

The list below contains all (Dwarf)Planets of the solar system and the sun, turned into lithophane lamps. All of the lamps below are original creations.

There are versions with the thread at the south pole (for standing use) and upside down versions (USD) with the thread at the north pole (for hanging use). 

Sun	Mercury	Venus Atmosphere
Venus Surface	Earth	Earth Bathymetry
Earth Political	Earth  Fishworld	Mars
Jupiter	Saturn	Uranus
Neptune	Pluto

Moon Lamps

The list below contains several moons of the solar system, turned into lithophane lamps. All of the lamps below are original creations.

There are versions with the thread at the south pole (for standing use) and upside down versions (USD) with the thread at the north pole (for hanging use). 

The Moon	Io	Callisto
Europa	Ganymede

Lamp Bases

Printing the Planet or Moon of your choice is only a part of creating your own lamp. You'll also need a Lamp Base to illuminate your Planet or Moon. I am providing several different Lamp Bases, all with a matching M12x1 thread. All of the Bases below will work for all of the Planets and Moons. 

All bases include a built-in mounting hole sized for an 8 mm diameter ring. Alternatively, you can pass a thread or wire through it to secure a fairy light. Via this mounting hole, different applications such as fairy lights, earrings or keychains are possible.

Links to shops are only suggestions on where you can find parts. I am not connected to any of the linked vendors and don't endorse them. Links are also supposed to show you how the required parts are called and look like. 

Fairy Light Base
String together as many planets and moons as you like with cheap, off-the-shelf fairy lights. Great for your christmas tree as well as any other around the year decoration BOM: 1x generic thin, two wired fairy light. USB or battery powered, e.g. from Amazon Printed Parts: 1x 025_fairy_light_base 1x Planet or Moon of your choice Assembly: Place the LED in the center of the base, guide the wire through the slots on the side Bend the wires slightly outward to keep them away from the thread Optionally, use hot glue or super glue to fix the LED in place. Works well without glue, though. Thread the planet or moon onto the base. Make sure not to squish the wires.
Button Cell Magnetic Switch LED PCB Base
The illumination option of choice for any sort of wearable: pendants, earrings, keyrings, etc.  BOM: 1x 1.0x8.0 mm jewellery ring, e.g from Aliexpres or Amazon 1x Button Cell Magnetic Switch LED PCB with a diameter of 10mm or less. Right now, there are two bases for PCBs with a diameter of ~10mm and ~7.6mm. You can find these on Aliexpress. E.g. 7.6mm, 10mm. Printed Parts: 1x 025_pendant_base_d*  1x Planet or Moon of your choice Assembly: Insert the 1.0x8.0mm ring in the base holes and connect it to your earring/keychain/... Close the ring with pliers Squeeze the LED PCB inside the Base. It should be a snug fit and the PCBs should not come loose. Thread the planet or moon onto the base If you bought LEDs with different dimensions, feel free to reach out and I can adapt/add Bases.

 More Bases / Different Light Options?

There's certainly more applications and illumination options than the few I came up with. Feel free to suggest new base options are ask for different dimensions. Also, I uploaded the Fusion 360 source files of my lamp bases. Feel free to adapt them to your liking. Remixes are always very welcome!
