Diveboard v1

Summary

Derived from the Original OpenDive design, Diveboard v1 is my first attempt at unifying OpenDive and Google Cardboard.

Specifics

This design is physically compatible with the original design and accessories, including the phone brackets, but includes several new features:

The visor

• Rounded edges
• Rubber band anchors
• A top elastic tensioner
• An internal cutout for a 0.5" round magnet
• An external track for the Google Cardboard click (also a 0.5" magnet)
• Optimized for the Nexus 5 screen

###The button

• Attaches to a neodymium magnet, runs along the external visor track, and provides a significantly upgraded click design.

The Rear Clip

• Includes a top elastic tensioner
• Includes a platform to hold a small battery powered USB charger (since both OpenDive and Google Cardboard eat through battery life)
• Includes side channels for the elastic to help hold the charger under tension

The Side Clips

• Although fully compatible with the clips from the original design, I have rounded the edges on the side clips.

The Lens Holders

• The lens holder is also compatible with the original design, but I rounded the edges on the "outside" to simplify insertion into the visor. Note that left and right are identical, so I only included one holder (so you'll need to print two copies of this).

Printing:

I have already fully printed this and can verify that it works very well. I've tried to minimize the need for scaffolding in the design, but unfortunately there are still areas where this is required. I printed this on a Replicator 2 using PLA. The lens holders and button I printed on high (0.1 mm layer height) with 2 shells and 20% infill. The remaining parts I printed on standard (0.2 mm layer height) with 2 shells and 20% infill.

Other items

• 25mm diameter, 45mm focal length acrylic lenses (Amazon)
• 1.5" elastic (Amazon)
• 0.5" neodymium magnets with a countersunk center hole (Amazon)
• #4 wood screw (Home Depot) to screw the magnet to the button
• Felt (Michael's) as a soft buffer for the screen
• Air conditioner mounting foam (Home Depot)
• An 18650 USB charger (Amazon)
• Hot Glue Gun
• Rubber bands

Would love to hear feedback if you have it!
