[Galaxy S III Accessories] Beemer533:
So after getting my new S3 a couple weeks ago I decided I wanted a dock for my truck to be able use navigation, music, etc a little more conveniently….

I was really surprised to find out that Samsung has not made an S3 specific dock yet….

After doing some searching, I found a thread here that showed the Infuse 4G car dock worked (thanks ookba!), so I picked one up from ATT last week to play with.

While it does what I want, I couldn’t use it with my Aduro shell holster case as it does not come off easily. In addition, I couldn’t mount the dock where I wanted in my truck.

So I decided to make my own dock and mount; hopefully someone here can benefit from this. This won't win any beauty awards, but it works.

The materials I used are as follows:

1/8” black Kydex (McMaster-Carr PN 8650K112)

Cannibalized Infuse 4G dock

Pro-Fit Toyota specific VSM G3 mount – This was sort of a mistake; I didn’t look closely enough where the mount was intended to be installed into my Tundra. The mount was made to be installed on the passenger side of the radio which is way too far away for me. So I ended up using the parts, but as the kit was $50, I probably could’ve done it cheaper if I was paying attention.

1/8 x 1.5 x 6” aluminum strip (Home Depot)

In addition, So I did not melt my expensive S3, I needed to make a replacement that I could use to form the Kydex with, once I heated it up; For that I used the Incipio case that I had first bought, but didn’t really like.

I also got some polyester casting resin and activator from an art supply house to make the form.

(Black electrical tape placed over openings to keep resin from leaking out)

After about 24 hours I had a "new" GS3! This picture shows the new resin S3 in the Incipio case...

Out of the mold. Note that the textured side of the Kydex is what contacts the phone; it almost feels soft.

Next I needed to fit the USB portion of the Infuse dock onto my cradle; In order for my S3 to slide onto the USB port, I had to mill the back of my cradle until the phone slid onto the USB smoothly. I ended up taking off nearly 1/16” from the back.

Once that was done, I cut out the center portion of the Infuse dock connector so I could fill it with epoxy and make it a bit stronger. I also had to grind down the bottom a bit to make it flat.

The scary part was actually gluing the 2 pieces to together so the USB plug lined up with the phone; For this, I had to use the actual phone and not my resin mockup…… Fortunately I did not end up gluing my phone to the dock!

Not the prettiest, but fully functional!

I did polish up the edges so they were smooth with my Dremel.

Here is the dock with the Pro-Fit Lock Plate (PN BR202-LP) secured to the back. You can also see that I molded the top of the cradle over an Exacto knife handle as a retainer for the phone.

With phone

I may cut off the tab at the top, as the phone fits in nice and snug by itself, so I don’t think it is in any danger of falling out. We’ll see…

Next, I need a mount!

I hammered on a 6” strip of 1/8” aluminum to make my mount. You can see the Tundra Pro-fit mount below it… More on that later…

Here is the mount sitting on my dash

This was an experiment, but I decided to try using some Command wall strips to secure the mount to the dash.

Command strips installed, Pro-fit mount bolted onto the end.

Mount “secured “ to the dash….

This is the mount temporarily secured where I wanted it with the owners manual as ballast.

So how did it work? It worked pretty well actually, with just a couple issues: The mount vibrated around a bit too much while driving and was a little too close to the steering wheel; however the dock itself worked well. I will probably mod the mount to stiffen it up.
