X1/P1 Replacement Filament Cutters

Printable replacement filament cutter blades for X1 and P1 Bambu Labs printers. 

Use #4 hobby blades, I used these from Amazon (https://www.amazon.com/TIHOOD-100PCS-Replacement-Hobby-Blades/dp/B07QP8L1QG). 

The blades need to be snapped to ~12mm in length. I created a small printable jig to allow easily snapping them to the correct length with the help of a pair of pliers. 

Please provide feedback if you give this a try. I am only one person with one machine, but I have tested with 1000+ filament changes and encountered no issues. All feedback is welcome. 

Print Settings:

• I recommend printing out of a material such as PETG, ABS, or ASA. I used ASA. PLA may work but I have not tested it so try at your own risk. 
• 0.12mm layer height highly recommended as it makes supports unneeded. 
• Use Arachne wall generation to ensure dimensions are preserved, I had issues when printing with classic wall generation. 
• 3 walls, 100% infill. 
• Brim may be needed due to small contact area with the build plate. 

Post Printing:

• If you used a brim ensure to trim any excess  so the cutter will properly fit. 
• Once you have your blades cut to length they can be inserted and secured using your glue of choice or by heat insetting. I found Gorilla brand super glue was effective. 
• Insert into cutter arm as normal ensuring it actuates smoothly. If it does not you may need to lightly sand the print. 

I have attached STL and STEP files as well as my ASA Bambu Studio project.
