If anyone needs the 60mm fan filter meshes by themselves and doesn't need screws, I can post those in an envelope instead of a 500g bag. Contact me directly as the da-Share shop cart doesn't have that as a postage option.
The good news is that fans, vents and mesh pieces are are back in stock.
The not as good news is that Australia Post have changed their cut-off times to 4pm at the PO and 12pm at mail boxes! This means that even if I post the same day as you order, there will be an additional day to factor into the delivery time.
