Shrunk the previously-validated 02004-004 PCB design by removing the hole pattern and adjusting the components slightly, creating the 02004-005 PCB shown below, which is 43x21.5mm. As a test of OSHPark's fulfillment speed, I ordered 3 of them (normally for 3 with free shipping) with their Super Swift Service (half the processing time) and added 0 2-day Fedex shipping. It should also be noted that OSHPark lets you reupload and overwrite your designs (provided the new one is the same size) up until they are panelized.
