So a while back I picked up a safe for my guns. It came with a carpet covered rack. I didin't like it so much because of the fact that it was made to fit rifles without optics.

In this project, we're going to make our own barrel blox to accommodate different sized rifles. We can move these barrel blox around the safe since they are magnetic and also have a modular function.

Techshop has great design software such as Autodesk Inventor. I also had to use their Maker Bot Replicator 3d printer which is now one of my favorite tools Techshop has. 

Step 1: Tacticool weapons.

Here is the safe with the stock barrel rack. Not so supportive. It will hold your grandpa's gun but not the new fancy shmancy tacticool ninjafied weaponry of today. Its ok, we can build something better.
