Decided to take a few leftovers from around the house and build me some new fans for the inside my tanks. I just worry the air is getting a bit stagnent with no movement. While there are two 2″ holes for vents on top, there should be a bit more air circulation inside the tank.

I have a bunch of 2″ Black Snap Bushings from HEYCO. Model SB-2000-26 for those who care. Got a pack of 100 on Amazon and so far I’ve used maybe 40. As you can guess I use them for the vents on my tanks, along with some No-See-Um Netting. I thought perhaps I could use these to make some  50mm Computer Fans more frog friendly.

Generally I’d just drill a hole in glass, Let the netting be pressed into place by the bushing, and then pull the netting till it’s taut. But in place of glass, I decided I needed something rubber.So I got me some Danco #39 O-Rings to keep the netting in place and wrapped some ponytail bands for good measure.

To clean up the edges I cut off the extra netting and then burned off the fray. Some glue under the ponytail band would probably be best. But for now I’m making it easy to remove the netting if necessary.

The adhesive I’m using at the time is Professional Welder which  is just what I happen to have around the house and seems to work pretty well with different types of plastics, but melts rubber. As you can probably guess I used the adhesive to put two of these bushings on either side of the fan. Since the fan is 2″ and the bushings are 2″, it’s works great!

Of course you need a way to attach it to an arm. And for that I got this Orbit 1/2 in. x 6 in. Cut-Off Riser. Just cut off the piece you need, then slice a groove in the top to hook the edge of your fan. The adhesive actually works great for this if you apply it liberally. I kept the riser in place with a rubber band and by the next day it was hard as a rock!

I have a few more steps to go to get these mounted to the tank, but so far these are looking pretty good. I was considering wrapping these in coco-fiber and trying to grow moss on them. But I’m not sure it it’s worth it.
