I have contacted the original manufacturer of the case screws for the A3000 and arranged an order of 50 sets. There will be custom made to order and are brand new sets of 4 screws and the matching washers. If you are interested in a set please email me using the contact form here on the site and let me know your name, location and number of sets you would like. I expect them to be here in a few weeks.
1 set of 4 screws will be $8 plus shipping.
UPDATE: The sets are sold out! I will arrange for a larger order after these come in next time. I had to raise the price to $8 a set due to the higher quote then expected when shipping to me is added.
UPDATE #2: The screw sets have been paid for by myself and shipped to me on May 31st. Once they arrive and I sort them into sets I will contact those who reserved them for payment and shipping information.
UPDATE #3: Screws are in!!! Sorting when I can and will be in touch soon.
