I have two printers and I really like printing with a nozzle 0.6mm for speed on a lot of tool accessories... but then I swap one of them for a "regular" print back to the 0.4mm and so on and I keep forgetting which nozzle is where after a few times!!

I looked up at some pre-made designs but none for this so I decided to just do it myself!! Got a few trial and error but this one works very very well!! ; )

I will mark the most common nozzle, 0.2, 0.4, 0.6 and 0.8mm.

The back as room for a round magnet up to 20.5mm and 2.5mm thick (ideally your magnet may be protruding a tad... the problem is there is no metal in the Creality Ender 3 V3 Plus and the K2 Pro... so options if you want to mount them:

- put a magnetic tape on your printer with a 3M double sided tape (I had some but not quite strong enough so I removed them)

- a double sided tape with another magnet (what I ended up doing)

- no magnet at all, you can use a strip of velcro and tape the other one to your printer

- mount it on your honeycomb grid wall system or something like that

- or just place it beside you printer or in a drawer with the rest of your nozzle but leave the indicator on the nozzle that you have on your printer !!

SETTINGS:

- NO SUPPORT NEEDED... I split the model so there were no "snags" on the panel to move freely

- I split the support and put some tiny pins to help reassemble it together and some CA Glue

- Colors: you can use the same color and just leave the numbers etched in: "V3a+b Bottom"

OR I re-split the bottom and use the slicer to put a pause (or a filament change if you have a CSF).

the parts for the bottom: "V3a Bottom" and V3b Bottom" are at angle to facilitate gluing back in place more easily

- BEFORE mounting back the Top with the Bottom, make sure to place the panel in between like a sandwich first!

I used a 0.6mm nozzle so my settings were at 0.3/0.6mm, the tiny pins printed but I had to use my small cutter to slim them back down (there are only 4 in the corners... the holes in the center is to orient the parts in the correct direction in case the holes were not fully aligned if you reversed the pieces.

** don't put too much glue to seep inside so the panel does not get glue in

My colors: I did not want the display to be too "bright" but blend in more... I just wanted the numbers to be more visible.

I hope you'll find this quick and easy print useful like it is for me !! Enjoy! : ))
