Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4287904.
Files for random bits of Hoth terrain, all modelled by me based on screenshots and Battlefield 2 reference videos.
Large Crate: Print 1x everything apart from 4x Locating Pin. Place the flat sides down against the bed, no supports needed. Use plastic weld to glue all the pieces together
Troop Transport: Print in one piece, minimal supports needed
Welding Cart: This was not based on any real reference, just on the fact that Chewie is welding in a few shots.
Print in two pieces, use plastic weld to print. There are many files for welding bottles etc available elsewhere
Mainframe: Seen in the background of many shots of the Hoth hangar bay. Print in one piece.
Hose End Cap: Can be placed on the end of black/grey 1.75mm filament to make refuelling hose etc. Accepts 2mmx1mm magnet to attach to models etc.
