Aluminum Extrusion Profiles for Case

[Airyck]

Hi all :)

I have a build and functioning Midibox Seq V4 with front and rear aluminum panels.

I have a MPCNC that I build with Wood CNC capabilities and also a laser (2.8W) which can cut opaque acrylic.

I'm planning to make wood sides with profiles cut to insert the panels and curved aluminum profiles but I'm having troubles finding suitable aluminum extrusion profiles for the curved parts.  I've look all over and can only seem to find the t-slot style ones in the U.S.

Did anybody have any luck finding a good version to use for making the quarter round curved aluminum profiles from a supplier in the U.S.?

Thanks for any help you might give :)
