Enclosure (Optional Extras)¶
These printed parts are optional extras used when building the V-Core 3.1 enclosure. Please note that these are dependant on panel width. Use the files with the appropriate panel thickness in the name (eg _4mm for 4mm panels).

Recommended print settings¶
All files are provided in the correct orientation for printing on a standard FDM 3D printer. In general the printed parts are quite forgiving, but are also quite large. If you suffer from drafts and/or poor bed adhesion you may need to use brims/rafts for some parts to prevent warping.
The following table shows the recommended print settings when printing any of the parts provided.
| Setting | Value |
|---|---|
| Perimeters | 4 x 0.45mm |
| Layer height | 0.2 - 0.3 mm |
| Infill | 25% |
| Supports | None |
Sacrificial layers¶
When slicing the files you will notice that some of the holes are covered. This is intentional, to simplify the printing process - those layers are there to trick the slicer into building a bridge there. Once printed those need to be poked out with a screw, screwdriver, Allen key or even a matching size screw.
