OK, this isn't a model but rather a gcode script to facilitate automated cold pulls to clear out your nozzle. I use it all the time on my Ender 3 and thought others might get some good use from it as well.
**What is a cold pull?**
A cold pull is when filament that is embedded in the nozzle is pulled out under a low temperature sweet spot so that it completely peels away leaving the nozzle with a clean inner surface. This is good for removing clogs and residual filament.
**Who is this for?**
This was written for an Ender 3, however should work well for any FDM style printer but your mileage may vary. If your bed size is less than 230mm then you'll want to edit the file using a text editor and change this line:
> G1 X10.1 Y200.0 Z0.3 F5000.0 ;Move to start position
The Y200.0 says to move the nozzle back 200mm, but if your bed is too small I'd say take the bed size and subtract 20 from that. So a 180mm bed size would be:
> G1 X10.1 Y160.0 Z0.3 F5000.0 ;Move to start posi
