Model Description:

Since the cutting edges of plastic bed scrapers wear quickly, I was not happy with the existing designs. They simply required too much filament to print.

That's why I developed this optimized bed scraper that holds replaceable blades. Each blade weighs just 1.2 grams - and since each blade has two cutting edges, only 0.6 grams of filament is required per cutting edge. It couldn't be more economical, and you can now replace the blades more often without feeling guilty.

I recommend my print profiles for this design:

1. As kit card
   Since this is a design for the Kit Card Design Contest, I created a Kit Card print profile.
2. As individual parts
   If you want to use the bed scraper right away, choose this print profile.
3. 32 blades
   With this print profile, 32 blades can be printed at once. If you want to print fewer blades, simply delete the unnecessary ones from the print bed in the print profile.

Print Settings:

This design has been optimized for printing with a layer height of 0.2 mm, so please do not use a different value. The first layer should have a line width of at least 0.5 mm. In order to get the sharpest possible blade, you should choose a smooth printing surface if possible.

Assembly:

That is very easy. Simply slide the blade into the handle. But be careful - the blades are sharp, so don't push them in with your finger, but insert them loosely and then push them all the way by pressing the blade on a solid surface.
