V2: The E3D V6 hotend block is slightly larger than the Ender 3 one. At the request of someone on the Subreddit, I made one for that as well. It has been tested and confirmed to work! The person in question discovered that some coins are the perfect width to use instead of washers. If you have any requests for different size hotend blocks you want me to make the tool for, just message me with the measurements

Disclaimer

This is not a remix by any means. But I still feel I need to credit Josh 3D Design(https://www.josh3ddesign.com/file-share) for his nozzle changing tool for the Prusa which is certainly what inspired me to make this. But keep in mind, it is just that - inspiration. This is my own design inspried by his. I wanted a few things different - first of all, I wanted a tool where all the non-printed parts could be sourced in a toolbox, and I wanted the holding part to be compatible with existing tools other than the printed wrench. So I just added some slots that should fit 2.5mm thick metal pieces(I used some thick washers) and made the space between open bottom.

Ender 3 nozzle changing tool

The tool I have designed here is made to help you change the nozzle on your Ender 3. In order to safely change your nozzle, you have to heat up the nozzle, HOLD ONTO THE BLOCK and screw out the nozzle. A lot of people(including me) had a habit of not holding onto the block and this can actually damage your printer in the long run. You might even snap something. So this tool lets you mount two pieces of flat metal to hold the block and then you can use a wrench(either an existing one or the printed one) to safely turn your nozzle! Remember, no matter what you print the wrench out of, the metal of the socket head will get hot QUICK! I would always suggest using a metal tool instead of the printable wrench if you have it, but the printable wrench works just fine.... just don't dawdle. Screw fast-ish, and if you feel like it's been on the nozzle for a bit, take it off and cool it down. Even if you print ABS, the plastic softens quick.

Non-printed parts needed

- 2x 2.5mm flat metal pieces that will fit in the slots. I used thick washers - 1x Socket wrench head, 6mm to screw the nozzle - OPTIONALLY a wrench tool, but there is a printed one too

Two kinds?

I included two versions of both files - a tool without a handle and a tool with. It all comes down to preference. Then I added two of the wrenches, one is half as long. I prefer the short one, but again, preference

My suggestion?

I suggest printing: - 1x MainPart.stl - 1x Wrenchyboi_short.stl
