good afternoon YouTube so one of my parts I need for my 3d printer filament dry box I need to make
some of these spool holders so I found these on Thingiverse I think this one's usable I printed
it out had a little problem with the very end and my retraction settings might be off a little bit
or the filament was starting to jam up but it kind of got messed up I think this would work
they're set up to take a skateboard bearing in here and you're supposed to press the bearing
in when it's hot and the plastic is still a little soft you press the bearing in and then you can use
a 5/16 or eight millimeter shaft to go through there and you punch one of those in each side
of your school run the shaft through and that'll support your filament spools but I got thinking I
could probably make a one-piece spool holder out of I have a lot of this UHMW ultra high molecular
weight polyethylene this is a two and a half inch piece and that's just bigger than the whole you've
got about two point one inch 54 millimeter inner diameter and I was thinking I could just take
one of these basically Center drill it like that one and then I happen to have my skateboard wheel
spindle jig which takes an 8 millimeter bolt so I could clamp that in here and then I just need to
turn a little step down from two and a half to two point one inches so take a little step off of this
to leave a flange yeah so first step I cut about a half inch disc UHMW this two and a half inch
nominal diameter and a hole in the middle then the base off the outside so it cleans up the saw cut
I clean out those small holes but there we go there's my disk there and I drilled one
sixty-fourth over 5/16 so I guess that's twenty-one sixty fourths so that makes a
nice nice fit on there get pretty good spin and then I'll cut the little shoulder on there so
I'll show you that next here okay there we go YouTube just doing a test fit here so I just
turned a shoulder down on that material and I think we get a pretty good fit I might have to
take a little more off but look at that perfect fit on there okay there we go YouTube's got two
of those done so these are 54 millimeter you know I think that'll work that's pretty low friction
I'll let the spool slide around a little bit and rotate freely and then I can stack multiple spools
up one next to the other apparently there's some variation in diameter here yeah about 53 looks
like around 53 millimeters there we go got the print right or collide oh spool fixed up about
53 millimeters okay here's my nylon filament spool and it's quite a bit different has a much
smaller hole and it's about looks like probably three quarter-inch nineteen millimeters and then
the other thing is if you can see there there's quite an offset between the edge of the or the
inside of the spool and the outside so it looks like you can just barely see that so I need to
go out about probably half an inch thick flange here especially you can see on that side it's a
spool is quite I don't know if that's where they strapped it in some place but it's pretty wobbly
you need to keep it operated from the spool next to it and from the wall of the box we'll use is
some of those I've got some more scraps of UHMW these were too small to use but that's about an
inch yeah I think that'll work so this is unusable material for my normal projects but one of those
on each side but I'll do the same thing I'll drill a 2164 hole through the middle and then I'll just
turn down a shoulder here to fit in there so I need to make this side I'll make this about 1/2
inch roughly 1/2 inch thick so it will do about Oh something like that and these spacers here
have enough of a flange on them I don't have to use my spindle I can just chuck them right up in
the 3 jaw turn them down and I've got one made here so here I've got my nylon school and that
pops right in there and I should have hey you can see there's just enough clearance across the
top there if we get it to get the camera view that should stick out just past the uneven flange there
on the spool so I got one more of these to cut and I think I'm ready to go thanks for watching
