I'm looking for a website that has some cool custom model instructions. I have a LEGO store near me and I'm able to buy pieces individually. I'm looking for more of a sci-fi ship kind of instructions.
There are quite a few individual sites out there offering that sort of thing, however one of the best I've come across is:
This is because the site allows you to catalogue all your parts and then search for other sets and MOCs you can build with your existing collection.
The Unique Brick LEGO Creations provides pdf instruction files, for a fee; but they don't seem to carry sci-fi creations.
This website has custom instructions, categorized by age and type. www.buildingexamples.com A nice feature is that they also provide Apps for smartphones and tables. Have fun!
