Warhammer 40K

Oh, wise and talented people of the internet! Found this excellent miniature storage/transport thing, but I need it for 32mm and 60mm but I lack the knowledge and knowhow to manipulate the stl file.

Anyone that feel up for the task?

Has anyone seen some good proxies for the old Elysian drop troops around? I've kind of got a hankering for making a unit of space paratroopers.
If not, I'll have to see if I can't hack up some jump packs to put on some of the space troopers I've seen around here.

I have been looking and unable to find a set of feathered wings for a Daemon Prince conversion to a Tzeentch Prince. Does anyone know of a file or any good at making a set that would fit into the back holes on the original model?

I'm looking to add some variety to my guard army, I really like the idea of adding the Tanith First and Only to my line up, but GW have discontinued the Ghost models. Does anyone have any links to good alternatives/proxies for them?

Also, I'm looking to get a bit more variety into my Vets, who are all catachans. I'd love if someone could hook me up with some ccw/pistol or shotgun arms that would fit style wise with them.

Anyone know a good model to stand in place for these guys? Looking to play around with an IG Kill Team list and need some of these before I drop cash on a box.

Cheers!
