MK10 M7 Nozzle for 3D Printer, 20PCS Brass Extruder Head Hotend Nozzles 0.4mm, fit 1.75mm D4/I3

I was looking to get a bigger nozzle than the stock 0.4mm nozzle that came with my Qidi X-Pro printer and came across this product. Although I was just looking for 0.6mm nozzles, for the variety of sizes this product comes with and at the affordable price, I figured Id give this one a shot. After all, it does include two 0.6mm nozzles for my two extruders. Anyhow, it was pretty straightforward to remove the nozzle on my X-Pro and install this new nozzle. I used the PTFE tube that was included with my printer (the Qidi X-Pro came with two addition 0.4mm nozzles that had PTFE tube attached to it and thats what I used). With the 0.6mm nozzle in place, I updated my Simplify 3D settings to 0.6mm for the nozzle -- and with Auto Extrusion Width, the Extrustion Width was set to 0.72mm. For my first test print, I decided to try it with PETG filament, extruding at 245*C on an 80*C bed and the extrusion came out nice and smooth. Although I have yet to try the other sizes, my original requirement was for the 0.6mm nozzle and so far, its working well. Ill see if this company sells a bundle of just the 0.6mm nozzles. I guess if theres something to gripe about, I have the following two gripes (albeit minor, at least to me): 1. I swapped out the nozzle on only one of my two extruders. The new nozzle protrudes out around 0.5mm further down than the stock Qidi nozzle on the other extruder. Very apparent when leveling the bed. Not sure if this is because my original nozzle has somehow wore down or if the length is just different. Not a big deal -- Ill just swap out the other extruder with one of the other nozzles that come in this set. 2. All nozzle sizes are all in one little ziplock bag -- so you have to carefully look at the little imprinted size on the collar of the nozzle to find the size youre looking for. Not a big deal but Im comparing this to some other nozzles I bought or my Creality CR10 v2 -- which were grouped into a small ziplock bag per size -- and each ziplock bag was labeled with the size. Overall, I would definitely recommend these nozzles if youre looking to change the size of your nozzle(s) on your Qidi X-Pro.
