TinkerCAD 3D Snowman for 3D printing G-Scale model railway
This is a model that I’ve made using TinkerCAD. A snowman designed for 3D printing on a home 3D printer. It’s been created to approximate G-Scale (1:22.5) for outdoor model railways. It’s also hollow so that you can insert an LED inside and have it light-up (assuming it’s printed with a light coloured PLA) so it can be used as a light-up Christmas decoration.
The photo below show the 3D snowman printed on a Wanahao i3 Duplicator Plus using white PLA.
To make it easier to hollow out there is a central cylinder which can be removed. The snowman arms are very delicate at this scale. If the size isn’t important then you may prefer to scale the model up a little which can be done within your Slicer software (eg. Ultimaker Cura).
