Hi, since I did not find such a nozzle cleaner that would be in the correct place in relation to the head which stops after testing the first layer, I decided to make my own. a little bit I had to fiddle with because the nozzle releases the filament which at first stuck to the silicone tip housing but in this version it's ok, I have been using it for a while and there are no problems. Silicone hole size is as in the screenshots from Shapr3D, personally I even put a thicker one there, as for the height, it is not necessary to put exactly 7mm in that place, it can be shorter. Just try it :) 

I printed it in PETG and it's not melting ;)
