4 Preparation before assembling
4.1 Engraving
All panels are marked with the side they belong to.
For all the panels except the FRONT panel and the BOTTOM panel, the
engraving face. The FRONT panel has the “Ultimaker” engraving facing
outward. The BOTTOM panel has the engraving facing downward.
4.2 Sanding
Before starting the assembly, you may want to sand the panels slightly to
remove any burn marks/blemishes from the laser cutting process. You can also
paint or stain your Ultimaker Original. Be aware that paint will not cover the
brown cutting edges very well.
