Ultimate Magnetic Bed Scraper Spatula with Printable Blades

This is the final version of a bed scraper that evolved from a much simpler model I designed years ago. I created it by combining features from several other models I found online, but none of them included everything I needed. 

It has replaceable blades, slots for neodymium magnets (especially handy for the Prusa CORE One printer), and a hole for hanging on a hook. 

Magnets

You'll need 2-4 neodymium magnets, 6 mm in diameter and 3 mm thick.

There are three magnet slots on the top and one on the bottom. I found that using just one magnet in the center top slot and one on the bottom holds the scraper well, but if you need extra grip, you can install all four.

For easy magnet removal, there are push-through holes on the opposite side. You can use a vise to press the magnets into place.

Blades

The blades are printable in plastic so they won't damage your print sheet. They are also replaceable, and each one has two usable sides. You can flip them when one side wears out. 

• For printing PLA and PETG parts, I recommend using blades from PETG
• For ASA or ABS prints, use blades printed in ASA or ABS.
• Use the PrusaSlicer project file to edit the text that labels the filament type used for the blade.

Print Settings

• Print the handle in PETG, ABS, or ASA.
