Introduction: Silicone Cover DIY for ANY Smartphone

Picture of Silicone Cover DIY for ANY Smartphone

I recently bought a new smartphone, the brand and model is fairly uncommon(Archos 50c Neon).

I was looking for a flexible(rubber/silicone) cover similar to the one I had for my previous phone but these covers are avaiable in almost every store only for the most popular models of smartphones(usually some versions of iPhone, various Samsung, and more rarely LG, Nokia, HTC).

Being unable to find a dedicated rubber cover and finding universal wallet covers not suited for my needs I decided to try make myself a flexible cover for my smartphone. I opted for clear silicone because it's easily avaiable and because my phone was packed with 2 exchangeable backs(one black and one in a nice fluo yellow).

Step 1: Materials

Plywood(I had a leftover)

Silicone (a silicone cartridge for 2.8€, about 3$)

Plastic wrap(the roll used in the kitchen)

Water+Soap


Step 2: Internal Mold

I used a piece of plywood to reproduce the smartphone size and shape.

I selected a plywood similar in thickness to the smartphone, I cut a rectangle with the same dimensions and then I rounded corners and vertices using file and sandpaper.

I also traced with a red felt pen important references as the display area, phone jack, microUSB port, microphone, camera lenses, speakers etc.

Step 3: Wrap the Mold

In order to avoid the silicone to stick to the mold forever I decided to wrap the mold with plastic wrap. I did twice because I also added the detail of the bump near the camera lens.

I decided to be careful and avoid wrinkles on the back side and be less careful about the display area that will be removed later.

I also used a little of water+soap to help avoid the silicone to stick too much to the mold.

Step 4: Add Silicone

Now you have to cover the mold with silicone, and this could be done in different ways but I tell what I did

I put a generous ammount of silicone on the back side of the mold, then I used anothe piece of plastic wrap.

I layed this plastic film on the table and put the mold back-down on this plastic wrap, then I applied pressure on the mold with my hand, this pressed the silicone between 2 flat surfaces obtaining a nice and uniform back side. At the same time the excess silicone exceeded the mold sides. Probably it will exit only on the sides and not on the corners, so If needed you have to add more silicone at corners.

Ad this point I used the plastic film( basically wrapping the mold+silicone) to obtain the cover sides and used fingers pressure to model the result.

Then let it dry.

Step 5: Remove the Mold

Unwrap the external plastic film

Use a cutter to cut out the desplay area.

Then extract the plywood mold through the display area.

Remove any remaining plastic wrap piece from the silicone cover.

Check it's actually dry and not still sticky before placing it on the actual phone

Step 6: Cut Out Holes

Put the cover on the phone and check the required holes position matching with the phone

then put the cover again on the plywood and using the cutter cut out the holes.

I'm trying to make a silicone cover for some switches. What brand did you use? Thanks

To be honest I can't remember the brand, it was just a regular cardrige used in silicon gun also for bathrooms and kitchens. I will check the brand as soon as possible.

That's cool if you ask me... with the poor quality in electronic cases these days, I would say that is a grand idea!
