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).

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.
