This is a redesign of this awesome scraper (https://www.thingiverse.com/thing:4167076).

I decided to make my version because I needed the scraper to be more robust and grip the blade well. Also for this reason the axis is now transverse, you can use a skewer stick or a plastic ice cream stick.

To fit the central piece you must insert it from the side and then rotate it 90° on the cylindrical part of the piece.

I hope it helps you and try to make your 3D prints things that work for you.

nice prints!
