Print your own 20x20 profile extrusion

[curious aardvark]

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:
