yes good morning YouTube so I need a piece of foam this is gonna go in my filament storage
box and what I need is a piece of foam about twice that thick that I can put on the lid of
the box and to sit down on the filament spool to put a little bit of friction on there to
keep it from spinning too fast so I have a sum of this corrugated packing foam and I find if
you cut right down one set of Peaks you can flip that over and move it over half cycle there and
that's about the thickness of the foam I need and this is fairly saw because I need to have
it push down on the spool to provide a little bit of friction there so let me cut this other
one here and I'll show you what I'm gonna do okay there I have my two pieces and I find this is just
a little bit narrower than the filament spool and what I have some of this spray on adhesive so I'm
gonna hit the surfaces there with just a light mist I'm basically making myself a thick piece
of foam I could probably go out and buy a piece of foam but this is all I need okay give it a
light spray of spray adhesive and just stick them together and a good squish yeah I think
that'll hold I mean it's not a high-strength set up any means fact is how they make this foam is
it's originally one piece this thick and then they punch fingers in here all the low points
have fingers pushed in and it ends up making a straight line so they actually cut this it with
a straight line and then you take the fingers out and that's what leaves the curves in there
so I'm just putting this back together like it was originally just cut off the two ends I don't need
and then just take this guy and I'll cut him like right in the middle I got two foam blocks there
so let's go up and take a look at the printer filament boss what yeah so this is what I'm
going to be doing with these foam blocks you can see I've got one just glued on to the lid of the
box and then that foam rides in the valley of the filament spool I'll show you here there I've got
one here and the idea is that foam block just kind of sits down inside of here and puts just
a little bit of drag on the filament so that when the printer pulls out a length of filament really
fast that wheel doesn't keep spinning so here's the the side of the printer here and got a 12 inch
300 millimeter travel front to back and if it's got the filament pulled tight back here and then
it's got to move the stru door clear to the front of the printer if it's moving 100 millimeters a
second in three seconds it's going to pull out 300 millimeters of filament and that's going to
get the spool down here is gonna you know that's going to do a couple of revolutions you know pull
in a foot of filament off that spool yeah in fact the other thing I'm going to do right now
you can see I've got the filament coming off the bottom of the spool first I tried coming off the
top of the spool so that it came straight into my feed tube over on the side and in that case I was
having problem with too much filament spooling out the spool would get thinning and and then
you would get too much filament and it would come off the spool so I switched it so it's feeding off
the bottom that with the foam seems to work what I want to try to do is I'll flip the spool over and
let let it feed off the top because if I feed off the top I get a little less friction going into
the tube because the filaments coming straight off and going out through the tube instead of
coming up and making that band I figure with this open cell foam that adds just a bit of friction in
the right spot because that friction keeps the spool from freewheeling and I'm getting rid of
the friction over here that really isn't helping anything these feedthroughs here you don't have to
clip the filament down to the spool the filaments held out here in the feed through tube and then
the sponge on the top keeps the spool from spinning so the filament doesn't unwind itself
just sitting in there and you don't have to fool with filament clips and all that stuff the only
time you have to clip it is if you're taking a full spool out and going to put it someplace and
you need to do something with the extra filament but otherwise it holds the filament in place and
you don't have loose ends and you don't have those big rat's nest so filament inside though
yeah I think this is getting pretty close to an ideal setup here so I'll show you what it looks
like when I get a little farther on here get it all wrapped up and as always thanks for watching
