from blender to 3d printed what's up i'm jonathan and welcome to make tales where
i'm sharing my maker journey to help you go further in yours
so don't forget to subscribe and hit that little bell icon to never miss an
opportunity to keep making this video is all about showing you a short workflow
of how to import something into blender do a minor modification to
it and then export it out for 3d printer so
the 3d model that i'll be modifying is devin's little tough hook here go
check him out at make anything his channel is amazing
so once you find a file that you like go
ahead and download it this can be an stl or an obj and then from there we're
going to go and work with it within blender
so here in blender we're going to go ahead and import
our object that we just downloaded so this is going to file
import and here if you have an obj you're going to click this obj file
and if you have an stl click the stl so i have an stl here so i'll be
clicking stl going to where i have this file
and importing it in so once imported you can see that we have
our little 3d model here now the edit i need to do is i have a
custom pegboard that i've laser cut and my holes are exactly 25 millimeters
away from each other so i need to bring these closer to each other
and on top of that i would like to put a little offset
of the size on these pegs that go in because my 3d
printer makes these 0.2 millimeters too big on top of that
this is set for a four millimeter pegboard
and my pegboard is only three millimeters thick so let's go and do all
those changes just before we get into it if you don't
know blender that well i do have an entire blender precision course here on
my channel so go check that out if you feel like you need to understand
blender precision workflows a little better
with that said let's go ahead and do my little changes so to start off with as
you can tell if we go into edit mode the geometry is
quite busy now this is probably going to
happen with a lot of models i'm just going to quickly delete this
cube here and the way that i find that for a good eighty percent
or seventy percent of models just select all the edges
hit x go limited dissolve and what i have it set here too is five
is far too much if i go down to 0 here and then you'll see if i just go up once
that's almost all i need so i've got 0.1 done
and that there is basically what i'm needing so
that's that sorted with so let's give this a rotation on the x
of 90 and let's start my small edit so i first need to shorten down
what i've got going on here all i've done there is gone into x-ray mode to go
circle select to then be able to just select the
entire top half of these here with those selected i can
now go g constrain it on the y and go minus
one so this is now set for my three millimeter thick pegboard right
next up from there i know that these are 0.2 millimeters
too far that way and too far that way for my pegboard but i want to show you
how i got to that so to show you how i got to that i'm going
to just quickly create a plane and i'm going to set this plane to 25
millimeters the reason why it's this 25 is my
whole centers for my pegboard because they're custom made
is 25 millimeters exactly so i'm going to use
cad transforms here i'm gonna go g edge centers from this edge center to
that edge center and the reason why i've done this is
because if i move this now on the z downwards i can use this
as a reference object for the move that i want to do so i'm going to select both
of these go into edit mode go into top view
go into my circle selection deselect everything
that i don't want so let's just do that right now so deselect
it all i don't need this one i don't need that
but what i do need is i would like to select
the rest of this little peg joint here so let's select all of that there
fantastic and now with that selected i can go back into my top view
and i can use my favorite add-on cad transforms
and i can go g with the vertex from here constrained on the x
move it to that point there and as you see there's the 0.2 millimeters so the
next one we don't need this one to do so let's go
ahead and do the last layer actually there's no there's
one more little layer that we need to do so let's deselect everything circle
select select all of this here
and select that over there too fantastic now i'm just going to go g
from here on the x by 0.2 fantastic and that there
apart from one last little edit that i would like to do is
it so let's go and do the last edit which is
as perfectly fitting as these are my holes seem to just be a little bit
too big or my 3d printer is making this nub just
a little bit too big and too hard to go in so i just want to go
ahead and circle select this here
as well as the same here
and i'm wanting to just shrink this in by 0.1 of a millimeter to do this i'll
be using card transforms once again and i'll be
using the scale operation and so let's go ahead hit s for scale
i'm going to go from the vertex lock that on the z constrain my next
movement to the x so that it's perpendicular
with this point here now i'm not going to move my mouse
after i click so then i can go minus 0.1 millimeters
and that there is the edit that i'm wanting to do so let's go and do the
same on this other side so x-ray
circle select make sure that nothing is selected before we go into circle select
fantastic circle select let's select everything that we're
wanting here so all of that there all of this
across here and all of that there down here and across here
double check that that is what i'm wanting
it is all right so let's go and do that once again
scale from this vertex don't move my mouse
shift z on the x move this to here click don't move my mouse z minus
0.1 millimeters and there we go that is the edit
completed so with that there i'm ready to go ahead
and 3d print this for those of you who haven't done the
precision course you might not have the 3d print tool so go ahead for that
you go into the edit preferences and what you're going to go
ahead and look inside of add-ons is type in 3d
and there it is 3d print toolbox now the reason why we're getting 3d print
to 3d print toolbox is because it's a great little checker
so here we're going to go ahead and check all and as you see we're pretty
much fine there we have some thin faces and
let's just go ahead go into face select select everything
and then go into the thin face so it says that this here are thin
faces now in all honesty i don't think that's going to be too much of a problem
here if we distort this it's going to give us
no problem make it manifold and let's check everything once again i don't
think that's going to be a problem but we have to keep an eye out when we
turn and put this into our slicer let's see if these faces
give us a problem so with that there that's how to go about and
easily edit something now the other reason why
i use the 3d print toolbox is because it has a great
stl export function so here in export all you have to do is select your object
say where you're wanting to go so desktop accept is going to be using this
name here as well as the name of your file
and then if you've been working outside of the edit mode
make sure you apply the scale as well because it can give you some problems if
you don't so then we're going to hit export and
it's as easy as that the stl has been exported
let's go and bring this into our slicer and see what we get
so i personally currently still use simplify 3d just because i haven't gone
and plopped the settings into cura slicer
because i really think i'm going to prefer a cura slicer in the future but
for now i'm here in simplify 3d so here we have our objects there and as
you can see it seems to be all perfectly fine so
let's go and now let's just quickly check our print
procedure here and as you can see it looks like it has
come out beautifully now one other thing i want to show you is that you don't
always have to export this out as an stl you could always have it as an obj or a
different file that you prefer now if you're wanting to obj you can use
the file format export here or you can also just select
your object go file export and wave format
obj with that done you select where you're wanting it to go
and then from there you can go ahead and drag that file into your slicer as well
as most slicers also support objs and that there is the absolute basic
fundamentals of how to go about importing a file into blender how to
simplify it in the very simplest of ways and how to do some very
basic manipulation to the model no remixing
yet but that video will be coming out in the future
a huge thank you to my patrons you guys are
absolutely awesome and if you think i'm worthy of your support
i would love to see you there too don't forget that if you want to know how to
go ahead and design these i have a video for them
right there thank you for watching keep making and
let the quest continue
