Use all standard settings for a 0.2mm layer height. No Supports Needed

There are 2 lengths of vent clips, and please use the vent clip removal tool or you may break you louvre like I did :) Push the tool wedge part first above the louvre and under the clip.

The Mainbody has an trim inlay border that you can do a colour change for, just split the model to parts and select the trim in the object list.

You need 4x M3x8mm screws for the back cover.
