i printed one for myself and put the photos online
<linext_>
people search for "reseller ruler" (resellerruler.com) but they don't sell on ebay or etsy
<linext_>
mostly people buy them over the weekend
<linext_>
some people want the kit with 40" (100cm) rulers, which is a pain to ship
<linext_>
i make the same amount for selling the center for $12.99 as I do for selling the complete kit for $39.99
<linext_>
about i week ago i tried adding google ads so my domain (dimensionizer.com) gets hits but it's a little tricky to set up

linext_: You could hunt for a second ruler supplier which ships online, and maybe size up an alternate version that fits that ruler.
<linext_>
maybe, harbor freight usually owns the factories in china
<linext_>
i may just ask harbor freight to ship 100 to the store and pay $500
<linext_>
they don't do discounts for volume
<linext_>
for most of the buyers, it's going to be a single purchase, so i'm not really sure how long demand will last

wow that ruler thing prints in that orientation? with no support? sheesh there is like no bed contact
guso78k has joined #openscad
<guso78k>
linext_ did you research whether you break any copyright issues are aren't you worried about that from the very beginning ?
<J24k>
I'll print one of these as demonstration object how orientation matters.
<Virindi>
I would expect a good chance that it gets knocked over during the print with such a small contact area
<J24k>
you should use brim or raft
<Virindi>
sure. I don't like doing that because it leaves the print unclean
califax has quit [Remote host closed the connection]
<Virindi>
I figure that would be extra important when selling a print
<J24k>
a brim is not, and while you could print a raft from extra support material - nothing that a scrub on sandpaper would fix
<Virindi>
intuitively I think the orientation I would try first would be if you were to rotate the one in the picture by 45 degrees along the axis of the camera
<J24k>
you would have the top bridged
<Virindi>
sure
<Virindi>
but the inner face of the top is not a critical surface either
<Virindi>
dunno
<J24k>
it is where the ruler is sliding
<Virindi>
or
<Virindi>
I would assemble it from multiple slices as separate prints :)
<Virindi>
for example, printed pins and superglue
califax has joined #openscad
<J24k>
I made a microSD card storage where the first uses glue - and then i found you could clip them nicely together by using slight taper ( not using pins but rails)
<Virindi>
using multiple flat parts I would think would result in better squareness than the ruler sitting against two opposing slopes
<guso78k>
if you have a good method to remove support, I would even consider putting it plain on the headbed(plus seen from above) because of mechanical reasons in use-case. removed support is not seen once the metal rulers are inserted.

virindi, its nice! but you need additional screws. maybe you can even manage to add a diagonal 45 deg dovetail(one half male, one half female, ) so you get rid of screws

guso78, the idea is not patentable. it's a 2d adjustable T-square
<linext_>
the design and manufacturing process may be patentable
<linext_>
a brim is sometimes needed for the 45 degree design depending on the filament
<othx>

if your part is getting pushed by the nozzle, it's likely the extrusion width setting is too low

i wonder why people need that dimensionizer cross block - are they not able to put two ruler on top of each other .. or is that for selling 100+ different closing you need to photograph ( where you could simply put them on top of the ruler)

linext_: lol. Sounds also like planned obsolescence.
<InPhase>
Or inadvertent obsolescence.
<linext_>
at first i was just trying to lower friction
<linext_>
the screen printing on the rulers is actually very good
<InPhase>
linext_: It is probably the best behavior, but it will then loosen over time with metal wearing away plastic.
<linext_>
i've been using one ruler to "break in" the centers
<InPhase>
A more sturdy unit might press down lightly in the middle of the ruler.
<linext_>
yea, like a digital caliper's lock screw
<InPhase>
You could then get a nice wide open area that would wear very slowly. The plastic would fall apart for other reasons first, probably.
<linext_>
i don't think it'll do that
<InPhase>
Are you printing these with PETG?
<linext_>
some PETG and some PLA
<linext_>
transitioning to only PETG
<InPhase>
Yeah. My intuition says that's the better choice for this unit.
<linext_>
PETG doesn't heat up as easily so it's a little more difficult to break in by using friction against the test ruler
<InPhase>
You know, TPU might be fun to try once. It seems to be practically immortal, and will give you a different friction profile.
<InPhase>
Given the application to measuring fabric, this would probably work okay.

<linext_>
agreed
<linext_>
now that the weather is good and i can open the windows, i might use up the resin for my other 3d printer
<linext_>
resin prints can have good optically transparency compared to PETG or PLA

resin will shatter if you are not using some expensive tough resin. There are quite some lever with the ruler - so TPU may be forgiving if it get stuck somewhere

I packaged thrust too btw.. so it's no real use posting any 'fix', I think it's up to the gentoo maintainers probably, what they want to do with it
<teepee>
would you mind posting those notes on the issue too?
<teepee>
ah, there's a gentoo link too already, cool
<teepee>
sounds a bit different regarding the actual error though

I honestly have no idea of the exact workings and fixes to those errors, all I know is that it was better to just create packages for those submodules

indeed, I'd love to see the number of submodules reduced, easy to add but annoying to maintain builds
