Just because Scrap Mechanic is in early access doesn't mean the modding community is willing to wait for the final release. The Steam workshop is packed with hundreds of excellent mods, mostly focusing on adding even more building parts to the base game.
We're going to look at Scrap Mechanic mods and pick out some of the best that will work in either survival or creative. However, there is an issue with some of the most popular mods - the May 7th Survival Update broke various things - and while most parts will still work in creative, you might experience missing or misbehaving blocks in survival mode.
Scrap Mechanic Survival Mods
The first wave of Survival mods are now starting to appear on the workshop and these are tailor made for your survival mode saves. Both mods below are by a single author, 10k, and he has commented that they both work together.

This mod adds more craftable items to the base game, allowing the player to build several useful blocks without needing to salvage them directly. Subscribe onto download.
Survival Harvesting Boost
Survival mode likes to give set drops, this mod adds a randomiser to various items and increases certain drops further if you 'pick' instead of 'hit'. Subscribe onto download.
Scrap Mechanic Creative Mods

The Great Wheel Pack
This mod, brought to you by ikey07, adds a selection of new wheel types to the game which considering how much you'll be rolling around is good thing to have. If all you're looking for in a mod is to cruise around on rims, this lets you play with a near vanilla experience. Subscribe onto download.
Buttons and Switches Pack
Have a wall full of switches and can't tell them apart? Add a host of funky looking new themed options to help you identify which button opens the door, and which activates that kill trap. We're a big fan of that big red button and the mayhem you could trigger with it. Subscribe onto download.
Another mod by ikey07, this one brings a massive number of blocks to the table, and the walls, windows,and floors. It's everything you need to make a house feel like a home, right down to the white picket fence. Subscribe onto download.
Buoyancy Mod: Water, Helium, Hot Air, and more!
As of Scrap Mechanic's survival update, the water portion of this mod no longer works but if you're looking for more ways to get off the ground then the helium and hot air won't let you down. Subscribe onto download.
Do you feel the need for speed? The Thrust Mod adds 35+ detailed engine parts, some based on real world engines such as the SpaceX Merlin Rocket Engine. There's also a few cosmetic parts to pretty up your rockets, planes, or that rocket powered buggy that definitely won't crash... Subscribe onto download.
Non-essential Scrap Mechanic Mods
As we mentioned above, the Survival Update caused a lot of issues for the current generation of mods and we're still waiting for fixes on the majority of blocks. That said, if you play creative, most will have near full functionality. Combine these with the basics of, and the world is yours to create.
