Solar System Lithophane Planet Lamp Collection - ⌀295mm

Attention

These lamps are very challenging to print, they consume almost 1kg of filament and take 4 to 5 days per print. Do not start a print without preparation. Print a test model for both, the top section of the lamps and the bottom section. Only start the real prints once you have confirmed that both, top and bottom print fine. I found that some filaments are just not suitable for this kind of print. Treat the print profiles as recommendations. They did work for me, but do not assume that they will also work for your printer and your filament!

Also be warned that support removal will be a lengthy and annoying process. You will need needle nose pliers, a wire cutter and small hands (small enough to reach through the thread hole).

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 (this upload), ⌀205mm, ⌀150mm, ⌀75mm, ⌀25mm.

Requirements

All Lamps have a size of ~ 300mm x 300mm x 290mm. They should print fine on large scale printers such as the Prusa XL or Core One L. 
The lamps are mounted to their base with a M75x4 metric thread. The idea for the thread and also the thread dimensions are taken over from the Lithophane Moon Lamp with wide Screw Base by The Quicksilver. This means that his moon lamp as well as his mounting options are compatible with my lamps and bases. I am providing multiple different base options that all use the same thread. Choose the lamp of your liking and match it with any lamp base of your liking. All compatible lamp bases are listed below. You may either need a standard lamp base with a E14 or E27 thread or threaded E14 or E27 sockets. Some Bases also require M3 heat set inserts and M3 BHCS screws. There is additionally the option to use a a Bambu LED Kit as base.

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: 0.20mm

• Variable layer height is strongly recommended for the top and bottom section

• 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 12-15 to obtain a solid lamp

• Set seam position to aligned

• Activate Brim (Outer Brim Only) and set the Brim width to 5-10 mm

• These lamps require support for the top section!

Be aware, that slicing and printing 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.

Attention: the top section of the earth models (earth, earth bathymetry) and mars are tricky to print due to the low number of top layers and the heavy bridging in the top section. You may encounter holes there without supports

To avoid ruining a several day print in the very end, I recommend printing the test models provided. If it prints well, go for the full lamp. If you encounter issues, reduce print speeds or use smaller layer heights for the top section.

The bottom section is similarly challenging due to the large overhang there. Print the bottom test model to validate your print settings!

This is not a SpeedBoatRace print! Use conservative print speed settings to avoid artefacts! It's totally fine if your print takes multiple days 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. You can also change the outcome by choosing light sources with different wattage or 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. 

Before starting a multi-day print, I recommend printing the Solar System Lithophane Calibration Panel to test how your print will turn out. You are also by no means limited to white lights and filaments. Check the makes below to get inspired what color and light choices other makers made.

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 M75x4 thread. All of the Bases below will work for all of the Planets and Moons. Except for the Legacy Base and the Bambu Base, these are original creations as well. The Legacy Base is a direct remix of Frank Deschners's base from his Designer Moon Lamp. I only added threads for socket and lamp. The Bambu Base is inspired by Bambu Lab's lamp base for their LED Lamp Kit. Depending on which base you choose, you will need different hardware for assembly. You will find a detailed BOM and assembly instructions below.

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. 

Some lamp bases use snap-off support. The supports look like small ring segments, tabs or cylinders that should be removable with very little force and should leave you with a good surface. They are only tested with PLA/PLA+ filament. Using other filaments may make support removal more difficult.

Bambu Base
While I do not want to endorse BambuLab (since I am a huge Prusa Fan), this still is the recommended Base option since it is the easiest and safest to assemble. No electrical skills or wiring mains voltage required.  You can get the LED Kit either on the BambuLab Shop or (cheaper) on AliExpress. Simply search for LED Lamp Kit 001. This Base is a remix of the LED Lamp 001 Base by Bambu Lab. BOM: 1x LED Lamp Kit 001 - via BambuLab or AliExpress Printed Parts: 1x 04_bambu_base Assembly: Simply get the Bambu LED Kit 001, insert it to the Base and screw the Base into the Lamp of your choice.
Puck Base
This Base uses E14 or E27 lightbulbs, making it easy to maintain and switch out lamps. Additionally, you can use differently colored lightbulbs and even color changing lightbulbs. Some electrical knowledge (crimping ferrules, connecting lamp sockets) required. BOM: 1x E14 or E27 lamp socket with M28x2 thread, no strain relief - available at (european) hardware stores 1x Lamp wire with switch, 2x 0.75mm² - available at hardware stores 8x M3 threaded inserts 8x M3x8 BHCS screws 1x E14 LED Bulb  Printed Parts: 1x 01_puck_base_E14 or 01_puck_base_E27 1x 01_puck_base_lid 1x 01_puck_base_strain_relief Assembly: Install 8 M3 threaded inserts in the puck base. Use a soldering iron, preferrably with a heat set insert tool Screw in the E14 or E27 socket from the top. Secure the socket with the ring or with glue Insert the ferrules of your cable into the two connectors of the socket.  Install the strain relief with 2 M3x8 BHCS screws. Make sure there is no tension on the cables Pull the cable to make sure that the strain relief is seated properly. You should not be able to move the cable Install the bottom lid and fix it with the remaining 6 M3x8 BHCS screws
Legacy Base
This Base is a remix of the Designer Moon Lamp's Base by Frank Deschner. For this base, you will need a pre-wired, threaded E14 socket with strain relief. No electrical knowledge required. Here too, you can easily switch out light bulbs.  BOM: 1x E14 lamp socket with M28x2 thread and strain relief - available at (european) hardware stores or for example from Ikea 1x E14 LED Bulb  Printed Parts: 1x 02_legacy_base_threaded or 02_legacy_base_no_threads if your printer is well tuned, I recommend the threaded version Assembly: Screw the E14 Socket into the Base or secure it with the nut that should come with the socket
E14 / E27 Adapter
This is a set of simple, yet effective adapters, allowing you to mount the lamps to any lamp base that uses E14 or E27 sockets. The possibilities are endless.  BOM: 1x Lamp with threaded E14 or E27 socket - some Ikea examples: a ceiling mount, a metal lamp base, a large lamp base and this pretty cheap base. The adapter is by no means limited to Ikea lamps. They just happen to be the lamps that I have at home and I could test the Adapter with. Just make sure that the thread diameter of your lamp is either ~28mm (E14) or ~40mm (E27) and you should be good. 1x E14 or E27 LED Bulb  Printed Parts: 1x 03_E14_adapter_no_thread or 03_E27_adapter_no_thread or E14_adapter_threaded or 03_E27_adapter_threaded if your printer is well tuned, I recommend the threaded version Assembly: Screw the adapter on the E14 or E27 socket and secure it with a nut
Rock Base
The Rock Base is inspired by Kristian's Floating Moon Rock Base. In fact, I even started with a Remix of the original moon rock base. Due to unclear licensing terms of the original rock model, I switched to a different source. This lamp base is based on the High Quality Rocks Asset by P_4_N_D_A. For now, this base only supports the LED Lamp Kit 001. Supports for different sockets may be added in the future.  No electrical skills or wiring mains voltage required.  You can get the LED Kit either on the BambuLab Shop or (cheaper) on AliExpress. Simply search for LED Lamp Kit 001. BOM: 1x LED Lamp Kit 001 - via BambuLab or AliExpress Printed Parts: 1x 05_rock_base Assembly: Simply get the Bambu LED Kit 001, insert it to the Base and screw the Base into the Lamp of your choice.
