Welcome !
Gone are the days when you need to reach for that tiny screwdriver or order a 0.1€ part that takes 1 month to get to you just to change your Pinecil soldering tip on the fly. With this small adapter you can turn any M2x6mm screw in a quick release for you're nice soldering tips.
Print with a 0.2mm nozzle, use a small dab of CA glue to fix the screw inside the adapter, wait 5 min for it to set and you're done !
The original screw is M2x4mm so we will be needing a longer one for our task. If you don't have a M2x6mm screw around, Bambu sales a bag of 20 for 1€.
Enjoy !
