Inexpensive Desiccant Container for Gun Cabinet




About: "Better to have it and not need it than to need it and not have it."

I've been searching for a decent desiccant  system for my gun cabinet but while searching for one decided to make one in the meantime.

Every time I unbox a new product I save the desiccant packets in a sealed container for use later. Here's how I reused the packets.

Desiccant Packets
Hard Drive Magnet
Soap Dish
Rubber Bands

This build was too easy. The titles of the steps themselves could have been enough of an instruction. I struggled to add fluff text to the steps to make an already simple step more understandable.

Teachers! Did you use this instructable in your classroom?

Step 1: Drill Holes in Soap Dish

Drill multiple holes in the soap dish for better air flow. I got my soap dish from the dollar store so it was a really cheap flimsy version. There's better ones out there. Drilling holes too close together will cause cracks between the holes if you put too much pressure on the drill bit.

Step 2: Add Magnet for Simple Mounting in Gun Cabinet

Put the magnet at the bottom of the soap dish. This will make it simple to mount to any steel surface. This step may be skipped.

Step 3: Pack Desiccant

Pack all the desiccant that will fit in the soap dish. Packing it too tightly may make it more difficult for the packets in the middle of the pile to be effective.

I also wrapped 2 rubber bands around the soap dish to ensure it stays closed if installed upside down.

Step 4: Mount Desiccant Container

At this point the desiccant container is done. You may affix it to any metal surface, or simply put on a shelf. I added the magnet to this build to keep the container out of the way.

Soap Dish - $0.75 (you might find this cheaper)
Hard Drive Magnet - Free (harvested off old computer)
Desiccant - Free (harvested off shipped packaging)
Rubber Bands - Free (harvested off Broccoli bunches or mail)

There's ways to re-dry desiccant packets, but I think the amount of time in the oven is cost prohibitive (cost of fuel or electricity for 2 hrs of drying time). It might be better just to replace the packets from time to time.

I don't think this will last in the gun cabinet for long. It is simply a stop gap measure. It gets pretty humid where I live and I wouldn't want rust to take its toll on my "collection".

    I noticed you had pistols, in their holsters, on the inside of the door, how did you make that work? I've been trying to figure out a way to store them without having all of the boxes in my safe and it's getting kind of right in there.

    The door has 3 slots in it for a plastic bin. I simply used two of them to slide the holster belt clips into. You can see the rectangular slits just behind the top holster. "Unfortunately" I have acquired a few more pistols since that pic was taken. so I had to fashion another way to keep the holsters in the safe. I bought a cookie sheet cooling rack and cut the legs to about an inch on one end and bent the legs on the other end into hooks so they could hook into the highest slot. I then clip the holsters onto the cooling rack. I have slightly more locations and variations for holster placement. I have to figure out yet another method soon because I fear that I may be acquiring yet a few more pistols and the door hinge may not be able to handle that weight and will cause the hinge to wear prematurely. I'll take a picture of the door in a little bit. My wife is still asleep and I don't want to wake her with a camera flash. ;)


    Here are the rest of the images I promised you. I guess I just need to turn this into an instructable. There are open spots at the top of the rack for a .357 snubby, a Ruger SR22 and possibly sneak in a 9mm M&P Shield (maybe). But I don't think the door was build to take this much weight. The piano hinge is already making some screeching sounds.

    You could also use an ABS plastic sheet and cut slits in it and make a MOLLE load bearing vest panel and hang it here instead. That was my first idea.

    Nice one! Don't forget that you can buy silica gel desiccant in large amounts at hobby stores; Normally it's used to dry flowers, and is sold in 1-2 pound containers. A paper towel lining the holes in the container will keep the silica gel from spilling, but they will still pull moisture through it...

    I went to Michael's and they didn't know what I was talking about. I'll try the local florists. Good idea; thank you. I would make a little drawstring purse from an old T-shirt to keep the silica in one place rather than the paper towels though.

    You have lots of guns. Tough man.

    great idea, I usually just scattered them at the bottom of a gun box/safe. Just make sure you hermetically seal the door and the descant will last ALOT longer.

    1 reply

    I open that door way too many times in a day for the hermetic seal to be of any use (like house plants these things need constant attention, stroking and cooing). That being said, it's probably moot that I put this contraption in there.

    This idea has been rattling around in my brain for a few months and I just had to get it done so I could get it out of my head and free up some RAM for other projects.
