Tilt adjustable HSW mount for Buddy3D camera

HSW mount for the Buddy3D camera with tool-less tilt adjustment.

Bill of materials

Printed parts

All required printed parts are available as single STL for each variant.

• HSW-buddy-cam--heatset+M3.stl: uses 2x heat-set inserts + 2x M3 flathead screws for the Buddy3D camera mount to the grabber + 1x M3x55mm to assemble HSW mounts and the Buddy3D grabber. Uses the most amount of hardware, good if you're paranoid about the ability of the printed material to provide enough grip and strength.

• HSW-buddy-cam--M3+printed.stl: uses 2x M3 flathead screws for the Buddy3D camera mount to the grabber. Least amount of non-printed hard-ware needed.

• HSW-buddy-cam--heatset+printed.stl: uses 2x heat-set inserts + 2x M3 flathead screws for the Buddy3D camera mount to the grabber.

• HSW-buddy-cam--M3+M3.stl: uses 2x M3 flathead screws for the Buddy3D camera mount to the grabber + 1x M3x55mm to assemble HSW mounts and the Buddy3D grabber.

Non-printed parts

• 2x M3x6 flathead screws. M3x8mm will work fine as well.

• 2x M3x5x4 heat set inserts (optional, see printed parts). Other sizes should work, refer to specifications of your heat-set inserts. The model by default comes with 4.4mm diameter and 6mm depth, these values can be adjusted in OpenSCAD if needed.

• 1x M3x55mm screw (optional, see printed parts).

Printing

STLs come pre-oriented and with all parts.

• Material: PLA will work just fine, other materials are not tested but should not pose any issues as long as they're not flexible.

• Nozzle: 0.4mm

• Layer height: 0.2mm structural

• Infill: 15% gyroid

• Perimeters: 4

• Solid layers: 5 top, 4 bottom

• Brim: not needed

• Supports: not needed. There are 2 screw or heat-set insert holes printed horizontally. If you have bad experiences printing these without supports, you might want to add some.

Assembly

Refer to the model images and HSW-buddy-cam--assembly-ref.stl.

• If you opted for the heat-set insert variant, add heat-set inserts to the Buddy3D camera grabber (the partial cylinder with hexagonal holes).

• Remove the bottom of the Buddy3D camera and screw if to the Buddy3D camera grabber (the partial cylinder with hexagonal holes) using M3x6mm flathead screws. M3x8mm should work as well.

• Assemble the Buddy3D camera grabber and HSW mounting legs. Refer to the images and assembly STL for reference. 

  • For the printed variant slide the grabber over the long pin, then add the other HSW leg.

  • For the M3 variant, use an M3x55mm screw, socket recommended but flathead should work as well. Screw into one HSW leg, add the Buddy3D grabber and then screw in the second HSW leg.

• Add the lock pin through the hexagonal hole with the camera tilted at the desired angle and mount to the Honeycomb Storage wall.

• Connect cable and you're done. If the cable does not flex much or has a longer connection it might be a tight squeeze, you can tilt a bit more to provide some extra wiggle room, use a more flexible cable or an elbow adapter.

OpenSCAD

The following libraries are required:

• HSW wall and attachments lib

• BOSL2

Heat-set insert size can be adjusted with these parameters:

• heat_set_insert_hole_diameter

• heat_set_insert_hole_length
