Airtipper extruder Base Remixed

I own original Airtripper extruder and I like it!

Only drawback: it's difficult to mount, because the base requires the nuts and the head of screws at the opposite side. You can't mount with screws from the top, simply because they are not accessible with the screwdriver!

So, I slightly reviewed the base, in order to have the screws accessible from the top.
