Trying to upload .cdr in .zip, processing endless loop, pls wait
/edit: MIRROR the drawing before use, or you'll end up with mounting holes in wrong position, or worse, inlet/outlet holes on the wrong half of the block top.
I just did. Hehehehe, stupid, didn't pay attention to it, so MIRROR is the word if you wanna drill all the holes one the printed sticker side.
...back to the circular saw for new pair of top halves
Cheers!
