t-slot extrusion profiles
thingiverse
a set of 3 common t-slot aluminum extrusion profiles: 20mm x 20mm, 25mm x 25mm, 30mm x 30mm @ 10mm height. when designing my new printer, I needed a way to compare the size of the extrusions I wanted to use, so I whipped up this quick little sketchup drawing. you might find these useful if you want to get a hands-on comparison of how the sizes exist IRL.
