Print your own 20x20 profile extrusion
Had a thought a couple hours ago about a 3d printed frame for a very small printer.
So made up this profile to match the standard 20x20 aluminium extrusion profile.
Useful for testing brackets or attachments or strutnuts etc.
And also for making a 3d printed frame that works with standard parts.
I've also included a heavy duty 30x30 profile that uses the same sized channels and nuts.
Just download and adjust z-height in your slicer to the length you want.
:-)
In your slicer set 'outer perimeters to print first' for a stronger part.
The 50mm piece I printed at 0.3mm and 100mm/s is bang on - so now having ago at a 'fast' piece :-)
Same 50mm but in 10 minutes in stead of 20 :-)
0.4mm at 150mm/s
Also don't forget I tend to use a 0.5mm nozzle as well. Makes things faster and stronger, while still being fine enough to knock out fully functional Iris boxes :-)
Added 25x25 and 30x30 - but with the same size channeling:

I printed some of this out with a spool remnant and ended up with about 15cm of the 20x20.
Printed at 0.4mm, 205c and 150mm/s.
Dimensions were extremely good.
So I thought I'd snap it.
Well tat didn't happen - astonishing layer bonding.
I did make the mistake of giving it to my dad and sayimng:'see if you can snap this.'
2 minutes later, he'd used the metal balcony rail to wedge against the plastic and managed to snap it by leaning all his weight on either end.
lol - after 50 odd years I should realise by now that he treats the phrase: 'virtually unbreakable' as merely a challenge :-)
I reckon the 25x25 would be breakable only with tools or placing it between 2 bricks and jumping on it.
But the fact that neither of us could snap it by hand was still bloody impressive.
Nobody's ever described either of us as a wimp.
And it did not snap cleanly across a layer line, the break is spread across 2 or three layers.
Almost perfect layer bonding/
Ie: it's is easily rigid and strong enough to be used as structural parts for whatever you want to build - I'm planning on an all singing and dancing rotary axis for my k40 and maybe a mini-mini delta if that ever becomes more than a daydream lol
But, yeah, this stuff is ridiculously strongLast edited by curious aardvark; 05-06-2020 at 11:41 AM.
