Optimized Bed Scraper XL

This is the XL version of my popular Optimized Bed Scraper with quick-change blades. The cutting edge of the blade is 45 mm, a full 30% longer!

Each blade weighs just 1.8 grams - and since each blade has two cutting edges, only 0.9 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.

Print Settings:
This design has been optimized for printing with a layer height of 0.2mm and a line width of 0.4mm, so please do not use different values. However, the first layer of the blade should have a line width of at least 0.5mm. In order to get the sharpest possible blade, you should choose a smooth printing surface if possible.

The locking mechanism has been optimized for PLA, so I recommend this filament for the handle. You can also print the blades with PLA - as long as you don't scratch on a bed that's too hot for PLA. In this case, I would recommend a more heat-resistant filament, for example PETG.

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.
