i stocked up on some 0.6 nozzles so i could test
an extra fast profile i've been working on for months. and i'm finally there. i'm ready
to share it with you with a practical print. i'll explain it all on today's Filament Friday.
Filament Friday is brought to you by the generous donations of these patreon supporters. in a
previous video i showed how my extra fast 0.4 profile was giving me faster and better results
than the 0.6 nozzle standard profile and cura. now some people commented in that video, why
don't i modify the 0.6 profile. some even called me lazy for not doing it. but what you didn't
realize is behind the scene i have been doing that for months. on and off for months. been trying out
an extra fast 0.6 profile and i could not get the results that i wanted. Until now. well my
son showed me a prop stop. it's a block you put on your boat motor to stop the propeller from moving
so you can tighten or loosen the propeller. and i thought well i could 3d print that. he said
go ahead and try it. so this was my design i came up with. very simple but it's a perfect design to
print with a 0.6 nozzle. but i really want to see if i could print it fast. and that's with my extra
fast profile i developed here. so let me take you through the evolution of this thing and then let's
find out did i really make it faster with my extra fast profile. now you can buy one of these on
amazon for about 16 dollars so it's not like we're saving a ton of money. but it's the idea that we
can customize it to the way we want. i went to tinkercad and it didn't take long to make this.
i used the block and then i cut the slot and then i rounded the tip at the top. and then i took out
some plastic in the center with two holes just to make this thing a little easier to print
and use less plastic. i brought this into cura and realized it would fit on my creality ender2 pro
so that's what i'm going to use with a 0.6 nozzle. and just for reference the low quality standard
profile 0.28 with a 15% infill in cura. once i sliced that it said it would take 7 hours and 38
minutes to print. so i said that's my baseline so now let's go back and let's try the 0.6 nozzle. i
changed the setting here in cura. now i'm going to use the standard draft quality
which is a little rougher 0.32 layer height. i'm going to keep the 15 percent and now let's slice
that and what do we get; 4 hours and 20 minutes. a huge savings just by going to a 0.6 nozzle.
now let's go back to the 0.4 and i'll use my extra fast profile like i showed in that previous video.
it's my Filament Friday version 5.1 extra fast 0.28. I keep the 15 percent and i beat it again;
3 hours and 6 minutes. but now i have a 0.6 extra fast profile it's a 0.44 layer height. i'll use
the same 15 percent and it doesn't require you to change the setting of the nozzle it's all built
into the profile. so when i slice it; two hours and five minutes. so i've gone from seven hours
and 38 minutes down to two hours and five minutes with my new profile and a 0.6 nozzle. let's look
at it in preview mode. i'll zoom in here too. it's two walls in the standard profile. you can
increase that if you want more strength. i heated up the hot end removed the filament and then i
could remove the nozzle. then i grabbed one of the 0.6 nozzles and put it in my tool and tightened it
into the hot end. from there i used my e-leveler tool at each corner and leveled the bed.
the first layer went down very smooth. i was happy with that. and the print itself
looks really good. although i am getting some stringing and that's typically caused by the
PTFE tubing drying out near the nozzle so i need to cut off that last 20 millimeters and fix it.
actual time to print was actually less than estimated; 1 hour and 56 minutes and 26 seconds.
so now let's see if it fits. it slides on nice and tight and the prop definitely hits it and
if you want to turn the prop the other way just flip it over slide it on and the prop hits it
from the other direction. so now you can put it in place use the wrench to either tighten or loosen
depending on which side you put the block. this is going to work great. but i do want to make a
few changes. i may want to try a triangular design on the inside so it's a little stronger. and still
use less plastic. all the testing has finally paid off. so i'm ready to share the profile. i'll share
it as a 3mf file at a link in the description below. it'll include this file, the 0.6 profile,
and my ender 2 pro machine profile. now some people say why do i do it that way? and it's
very simple. because this way you can take that exact 3mf file, bring it into cura, and completely
reproduce what i showed you in the video. and you get a g-code file out of it and because it's on
a small ender two pro bed, that g-code file can print on any machine. or just about any machine
other than maybe a prusa. and it'll print right in the corner. so if you have a bigger bed it'll just
print in a corner. if you have a medium-sized bed it'll print in the front corner and also part of
the center. but that way you can reproduce exactly what i did and then if you have a creality machine
that profile will show up because you loaded it into cura. if you don't have a creality machine
just modify the creality profile to match yours and you're ready to go. so that's why i do it as a
3mf file. so you can completely reproduce what i'm doing here. go ahead download the 3mf file
at the link in the description below. it's free to download. and give me your thoughts,
did it work for you? if you like what i'm doing here maybe check out some of the videos that are
popping up. if i want to help support the channel patreon is one way. and if nothing else click on
