Mexican Train Roundhouse Domino Game Piece 3D print model

Roundhouse dimensions:

100mm wide X 100mm long X 35mm tall

Approximate minimum 3D print times for FDM (filament) printing:

Base- 1.5 hrs @ .2 layer height Top- 7.5 hrs @ .2 layer height w/ support

Note: Print times are approx. to give a general idea of how long the print will take. It will vary based on individual 3D printers and settings.

Print difficulty: Easy

Description: We weren't satisfied with the flimsy, boring, plastic octagon normally included with many domino sets for playing Mexican Train. This stylish train yard roundhouse gives your game night flair and lets your friends and family know they'll need to bring their A-game.

This train-inspired design theme features architectural arches as well as a raised train track which adds realism and allows for easy, multi-color 3D printing with a single color printer (more info below). It's also sturdy and functional with a platform on top to display the starting game tile and 8 places to store your locomotives or other train markers when not in use. It's also a fun and unique holiday stocking stuffer, party, or birthday gift!

Unlike many 3D meshes available for downloading and purchase, this model was designed specifically for 3D printing and should be fairly easy for anyone with basic 3D printing experience to print with a standard, desktop FDM printer. The example in the photos was 3D printed with a Creality Ender 3 using relatively inexpensive, but good quality PLA filament and typical, standard settings. Other methods of 3D printing should work equally well.

What you get: Two (2) downloadable 3D mesh STL files, one for the top, and one for the bottom, that form the central game piece for playing Mexican Train when joined together. STL files for other game pieces are not included.

3D printing suggestions and comments: For FDM style printing, PLA filament is recommended because it's easy to print with, and when printed properly, it will create a strong game piece that should last a very long time when used under normal conditions. Almost any popular filament type (ABS, PLA, PTEG, etc.) will work, but PLA is more than adequate and usually easiest to use. You will also have the most color choices with PLA.

A layer height of 0.2mm is recommended for a good balance of detail and print time, but any layer height from 0.1mm to 0.3mm should yield acceptable results. It is also recommended that you print both parts separately in their upright, default orientation. The top part will need supports for the arches. The bottom part may need a brim to prevent warping during printing. After printing, the two parts are designed to snap together and hold without glue, but glue may be used if needed. A properly calibrated 3D printer and a good print quality will ensure the best fit! YouTube is a good source for videos on printer calibration.

Multi-color 3D printing: It's convenient to 3D print this model in multiple colors with a small, simple, single-color FDM-style 3D printer. As well as printing the top and bottom pieces in two different colors, when printing the bottom piece you may change filament color at a layer height of 1.6mm, adding an accent to the train tracks as seen in the example image. If you want to go further, change filament color at both 1.6mm and 2.0mm layer heights so that the base, railroad ties, and the train track are three different colors (not pictured). Contrasting, wild colors are recommended. Remember, this is for FUN!!! :-)
