A lot of the same stuff you do! Daily stuff I run across that I see differently.
Going from left to right in the pic:
4 drill sleeve halves of different length with some model sprues, a wire nut and a 4 way tie down.
Both the bulbous shaped buildings are old style child proof door handles. One inverted. Both have bottle caps on them. The far right one has a drill sleeve and both have sprues also.
The back 3 are all plastic electrical gang boxes. The mech hangar is a double, the round one is a ceiling fixture and the right one is a single gang box. The hangar just has a cut out on the side, some sprues, a wire nut and another tie down. The round one has sprues and a small part of a sleeve. The single gang box is the HPG. The addition of 3 sleeve halves, and some sprues give it depth. The dish is based with a champagne bottle top with the top half of a small gatorade bottle with its cap and a small plastic cap inside. Bonus on the use of the gatorade bottle....there are small lightning bolts on the sides of the dish that SCREAM out to be highlighted!
The center round building is a pill bottle with it's bottom filled with glue to level off the top and several small tidbits of stuff and some sprues added. The round sprue in the center will look great with the Star League symbol inside of it. I may do another of these and make them gate keppers of a sort at the entrance to the compound.
