Half circle magnet algae scrubber

[jrawk1120]

So I've always loved curved takes. When I saw one pop up on marketplace, I had to get it. Oceanic 144g.

The only problem with these is keeping the glass clean. The rectangle magnet cleaners don't work well. I've tried at every angle.

I'm looking for recommendations on how to keep it clean without having to get wet every couple of days.

I'm no engineer but a tight I've had was getting material you normally find on the magnet cleaners. Have somebody that does 3d printing print a curved magnet cleaner and find some strong magnets, have them sealed inside and then adhere the fabric to it. I just don't know how to figure out the arc......circumference of the half circle. I just know the back glass is 57" and it sticks out 30".

However, if anybody has any ideas, I'm very open to them.

I've recently purchased some neodymium magnets from kjmagnetics as well as "Shabebe" Epoxy Resin from Amazon and "Let's Resin" Silicone rubber for mold making an Amazon. I want to make 3d printed mold for the silicone, so I can use that to epoxy coat the magnets.

You can use tinkercad to design what you want with the specific curve you need. Tinkercad is s fairly easy user friendly tool to use to design 3d printed things.

If you or someone can design up something they can put some small epoxy coated neodymium magnets in the print to make a curved magnetic scraper.

I have somebody in mind to do the printing who already makes reef equipment through 3d printing.

Any ideas on how to find the curviture?

Does the idea seem plausible?

You can use a flat blade magnet cleaner if you only go horizontal, that’s how I clean a bowfront tank. Takes some self training and discipline

I tried using my flipper on it with the blade and it just doesn't want to scrape

You can take a pic of the curve from top down. Upload the pic to photopea.com. or photoshop if ypu have it. Do your best to erase or use a brush with white color to trace around the curve. Fill in the curve with the black brush tool. The goal is to have a white only background and a half circle type shape that is black. Save as a png file.

Then you upload the png and convert to .svg. using https://convertio.co/png-svg/ this will save it as a 3d file someone can import into a cad software.

It sounds more difficult than it is typed out. This vid helps explain it more.

This is a super rough idea but after you have your pic on the photo editing program you want it to look like this when it's done. So the black part will become a 3d printable file.

Thank you for the tip. I don't have any of that software but I'm sure if I send a picture to the person printing it, they'll be able to.

I'm not very techy so this is a whole new world to me
