The Range Finder is made of just a few sketch profiles:
The Range Finder Holder
The Range Finder Holder is made up of one main sketch profile:
This profile is also available as a PDF.
Once the sketch profile has been created, it is extruded up.
- Holder_height = 10.5mm
The Range Finder Cover
The Range Finder Cover is made up of just two profile sketches.
This profile is also available as a PDF
The first is made on what will become the front of the cover.
Extrude the front profile
Now extrude the front profile by the case thickness (16mm).
- case_thickness = 16mm
Next, create an offset plane from the front face, and offset it by 4mm. This will create the depth of the case, and allow the cutout sketch to be created.
- offset = -4mm
Create Inner Sketch
Using the offset plane created in the previous step, create a new sketch and draw a rectangle. The rectangle is constrained by the 3.1mm offset from the edge of the cover body. This will create the area where the Range Finder board will be housed.
- offset from edge = 3.1mm
Extrude-Cut inner profile
Now using the profile created in the previous step, extrude-cut the profile to the back face. This will cut out the area where the sensor will be housed.
- extrude-cut depth to back face (12mm)
Create Standoff Sketch
Using the new inner surface, create a sketch. We will create a single circule with a diameter of 5mm. This will be used to create the standoff pole that ensure the board is the correct distance from the front of the cover.
- standoff_diameter = 5mm
Using the profile created above, extrude the standoff pole by 8.5mm.
- Standoff = 8.5mm
Apply a 1mm fillet to the front and back faces.
- Fillet = 1mm
