The plastic parts of Lighthouse are designed to be 3D-printed without the need for a lot of support material.

3D-model files (CAD files) and customization
To build Lighthouse you need to 3D print two different parts — a top and a base.

If you want to print straight away, you just need to use the STL files, but if you want to customize the lamp you can import the STEP files to your CAD software of choice. You can find the files at the bottom of this step of the guide.

Filament and the Environment

For Lighthouse, you need approximately 255 g (9 oz) of filament.

To minimize the negative effect on the environment I suggest that you find a plastic filament that is plant-based, such as a PLA-filament, instead of a filament made from fossil oil, such as an ABS filament. In general, a PLA-filament is less robust than fossil-based filaments, but I find that you can compensate that with a higher infill rate (higher density) of your prints.

Part Orientation

The parts are designed to be printed laying flat on the print bed, with the leg holders pointing upwards for the base-part, and with the side without the slot upwards for the top-part

Print Settings
I used these settings on my Creality CR-10 Mini 3D printer:

Layer height: 0.24 mm

Infill density: 30%

Printing temperature: 210 °C

Build plate temperature: 60 °C

Print speed: 50 mm/s

Wall and support speed: 25 mm/s

Support: Everywhere

Build plate adhesion type: Raft

Raft extra margin: 8 mm

Print Time

This is the time it took for me:

Base: 17 hours and 41 minutes per part

Top: 7 hours and 12 minutes per part

Stay Safe

As always when it comes to 3D printing, make sure you have your printer in a well-ventilated area to protect yourself from any harmful fumes.
