Advice? Nano Scraper

Does anyone have a magnetic scrapper/scrubber they like for acrylic nano tanks? I've got a biocube 14, i was previously using the two little fishies nano cleaner, but it wore out and was only so-so on stubborn algae. I bought a standard size flipper, but it is just way too big for this size tank and trying to maneuver around my Vortechs, and unfortunately the nano size only comes with a steel blade. Additionally, the BioCube has the curved front so the flipper is really only effective going straight left and right, and the curved corners are difficult for both styles. This one looks like it might do the corners, but doesn't have a scraper. Just hopeful that someone has a perfect all-in-one somewhere
