The alu extrusions came in at 132 EUR. But my frame is considerably bigger than an UMO and has more pieces (16 extrusions).
Note that I used 3030 extrusions. The 2020s are cheaper, but the modifications probably cost the same for both types (Around 1 EUR per mod, with up to 5 mods on some of my extrusions).
/Btw: I don't wanna hijack this thread. Yes, this printer is quite different from an UM2. I will reveal the details about it in time - for now the build is far from finished and will take some more time to produce anything. I will open a new thread once there's something interesting
