I'll directly message an offer to you, but I think you should try asking other forums/places rather than here. Not many people here (besides me) are traders, so you might not get offers here as much as you would on other sites.
Several trading-centered forums, like those on Backpack.tf
, could help you sell this and offer on it. But to be really honest, your safest bet for Fabricators and such would be as Muddy mentioned the Steam Community Market.
(EDIT: Fishy's fab has been purchased)
