LEGO Gale Crater

Description

It's a set of LEGO compatible baseplates, with two plate dimensions: 10×10 pins (80×80 mm) and 20×20 pins (160×160 mm)

They are designed to fit with regular LEGO bricks in order to create a martian terrain scenery.

Designing

I have downloaded the STL scan of the Gale Crater from

https://nasa3d.arc.nasa.gov/detail/gale-crater

and created all around with Blender, adding the base and the LEGO pins, the 20×20 pins version has 4 auxiliary pins for put a a flag on the crater.

The decimate modifier is used in order to reduce the numbers of the polygons from the NASA gale crater scan.

Sources in Blender format are available for download.

Printing advice

I have printed the models with:

  • 0.4 mm nozzle
  • 0.2 mm layer height
  • 30% infill
  • 6 perimeters (2.4 wall thickness)

I advice to use a 30% infill setting for better finishing of the crater surface.

Weight of the finished objects with 30% infill: 20 g (10×10) and 80 g (20×20).
