Slice Settings

Below are some recommended slice settings. We used simplify3D to slice these parts and generate the gcode. These parts were printed on a Sigma BCN3D using a .4mm nozzle and 1.75mm filament.

• .2mm layer height
• 220C extruder / 65c bed
• 20% infill
• 4 top/bottom layers
• 2 shells / parameters
• 60mm/s printing speed with 120mm/s travel

Tolerances

The top cover should have a friction fit to the case, but you might find it difficult to snap together. Tolerances will differ depending on the 3D printer. If you find the pieces are too tight, you may need to use a filing tool on the edges to loosen up the tolerances.

CNC Milling Acrylic

The lm-cover.stl part was designed to be CNC milled or laser cut. Although it can be 3D printed, the details on the top will not appear because they're produced via CAM tools. The STL and source file is available to download so you can adjust the CAM tools to work with a number of milling machines.
