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
