Unfortunately I don't have the cabinet 3d models with metric units. I do have metric dimensions for the MTMWW tower posted here if it helps at all. Edit: realized I can just switch to metric values in sketchup, here is the Center cabinet, you can round everything hole numbers without issue: The driver models and crossover components needed are posted in the BOM images in the posts for the respective designs. You don't have to use Dayton crossover parts, you can substitute similar parts from other available brands you can get easier in Sweeden as long as the values are within +-10%, the voltage rating on the capacitors does not need to match, just needs to be equal or greater. The Sku's listed in the BOM are for partsexpress.com, you can use those item numbers to look up the exact parts on their website if you want. I do not think ebay will let me mark items as gift on the customs declaration form.
