simple Scraper

I needed a small scraper to get of the filament and acetone from my heatbed. This is what I designed in a few minutes. It is far from perfect but it works well and fits the with the razor blades I bought at my local hardware store.
I printed it with 30% fill and 3 0.2mm layers. This seems to be OK.
for assembly you will need the blade and 2 M3*6 screws, 4 nuts and washers.
This scaper has been inspired by thing:13045. But has different screw holes so it will fit my blades.
