I saw a picture of a similar iPhone 4 case somewhere online a while ago and I traced it back to Bleach Black who makes a "Death Roll" iPhone case. I was ready to purchase one, but they haven't started selling them yet! That was when I though, what the heck, I will just make one myself!
To make my iPhone case, I purchased 1/2" tree spikes from Studs and Spikes. They are really easy to install, you just have to screw them together.
I also ordered a relatively reasonable silicone iPhone case from Ebay, it only cost me $4. I would suggest either Amazon or Ebay. You just have to make sure it is simple, plain, and nothing on it. Any color you want will do!
I started lining up and arranging my studs to how I would like it to look in the end. I used about 43 studs all together. Make sure they are evenly spaced!
Next, I took a pen and marked where each stud stood. This will help you when you have to puncture holes through the silicone.
Once you get the screw in from the back side of the case, screw the stud on it. To make the studs snug, you can use a screwdriver to tighten them.
There you have it! A studded iPhone case! Many people asked me if it hurts to hold it, but it doesn't. They wiggle around, and your fingers fit nicely between the studs. I love it!
Try It Yourself! If you end up making one you will love it as well!
