Aquarium blade scraper

I didn't find anything like this, so I draw it myself and decided to post it ( It's not beautifull, but someone may find it usefull )

It utilizes common utility blade (like the one in images) found in every hadrware shop (at least in central Europe)

I use 2x M3 heat inserted nuts and 6mm M3 bolt, but you can use regular nut and longer bolt and some washers.

If you need any change on this, let me know and if you find this usefull post a picture :-)

Note: nevermind the color change, I just used filament leftovers.
