Description
Oahu, HI dual color topographic map with a separate outline made for glow filament! Part of USA of Plastic collection.
Show off the outline of Oahu with glow in the dark filament or a second color!

The individual 3D printable 3MF files are cut for your convenience and fit together once printed. The files are in 3MF format instead of STL for smaller file size and in order to store separate land and water objects that are aligned for accurate dual color prints. 3MF is supported in Cura, PrusaSlicer, and other 3D slicers.
| File | Description |
|---|---|
| Oahu-dual.3mf ⭐ | Dual color model with land and outline features. The land has extra material going outwards that is the base for the outline to be printed on. Useful when you want to minimize the amount of material used for the outline due to abrasiveness of glow in the dark filament. |
| Oahu-dual-thru.3mf 🌟 | Dual color model with land and outline features. Outline features go all the way thru to the base of the model. Useful when the outline is in transparent or glow in the dark filament so that you get maximum light transmission. |
| Oahu-single.3mf | Single color model with land features and waterways as lines made for single extrusion printers. |
Print the models as is with a dual extrusion printer. If you have a single extrusion printer, you can either print the *-single.3mf model or run two single extrusion prints utilizing the Z-hop method. This model can be sliced in half vertically and printed sideways in two halves for an interesting effect as well.
You can scale the model up or down as needed to fit your printer size, the final map's scale will just be scaled accordingly. E.g. 200% scale on a previous scale of 0.4mm:1000m results in 0.4mm:500m
Download the optimized Cura print settings profile for topo maps here.
Cura may automatically scale the model by 10000% so you need to Select All Models (Ctrl+A) and manually set the Scale to 100% and X/Y/Z position to 0,0,0 for the models to show correctly. Merge (Ctrl+Alt+G) objects in Cura if you rotate them.
Printing this will test your 3D printer's XY precision, Z-axis stability, retraction, cooling, and oozing!
