I designed a simple nozzle size indicator that attaches to the P1 screen.

FEATURES

• display what nozzle you have
  • 0.2
  • 0.4
  • 0.4 hardened steel
  • 0.6
  • 0.6 hardened steel
  • 0.8
  • 0.8 hardened steel
  • empty
• Satisfying wheel to select your nozzle
• Easy assembly, no glue, bolts, etc. Just snap in place
• Mounts firmly
• Can be disassembled if needed
• Multicolor print even for those who do not have AMS.
• PLA is just fine, no need for PETG or any other material

PRINTING and ASSEMBLY

Print all the parts.

• AMS - this is straightforward, just print via my profile and you are good.
• NO AMS - I sliced it in a way that on the second plate which prints wheel you printer will pause just before it starts printing numbers. At this stage, change filament and then continue with the print to achieve multicolor print.

Take the main body and drop in spring into place as can be seen below.

Drop in the wheel in correct orientation

Slide it on the display - make sure it is really tight on it

Take the lid and slide it on from the right side. Observe ideally form below that you insert it correctly. This will snap in the place. There is also square hole which you can grab in a case you would like to disassemble it in the future.
