I'll chime in... had my kit for about 2 weeks now and will share my experience:

Tools

If you don't have some of these, I HIGHLY recommend them.

  • Flush Cutters. Fantastic for snipping and trimming zip ties, and great for cutting filament. They're inexpensive at less than $5. https://www.amazon.com/Hakko-CHP-170-Stand-off-Construction-21-Degree/dp/B00FZPDG1K/
  • Digital Calipers. You'll use these alot. Will come useful in the construction of the printer as well. Can find a decent pair for $10-$20. If you have a harbor freight nearby, they sell some decent ones that always have a coupon.
  • Bondhus Ball Hex Screwdrivers. I don't know people do it, but using those L shaped hex drivers are annoying and uncomfortable. Don't cheap out on these. Bondhus makes some of the best hex drivers in the business and are fairly inexpensive. https://www.amazon.com/Bondhus-10687-Balldriver-Screwdrivers-ProGuard/dp/B0006O4ADI/
  • M3 Tap - I don't know how widespread it was, but a few people received frames where the holes were not tapped (or if they were, they were covered in powdercoat afterwards), and had screws snap inside of them. You don't want this to happen... happened to me and is a pain to fix. I didn't want to deal with customer support and wait for a new frame, so I tapped the holes myself. Even if you don't need the tap, it'll come useful for a lot of projects since a lot of stuff uses 3mm screws. https://www.amazon.com/Tonsiki-Adjustable-T-Handle-Reversible-Threading/dp/B01M4J4GWL/
  • 3mm hardware kit - Again, you'll likely need some extra 3mm hardware if you plan on modifying the printer or adding on to it. https://www.amazon.com/Hilitchi-210pcs-Stainless-Socket-Assortment/dp/B014ONCP88/

    Assembly isn't too hard, and the directions are pretty good. My main complaint with the directions is that sometimes they don't explain what's important and not important all the time. I spent a lot of time building, taking apart, and rebuilding the base y-axis frame because I thought I did something wrong (it wobbled) to find out that you fix that wobble as one of the last steps.

    The 100mm distance that you're required to thread double nuts early in the assembly is absolutely critical by the end of the build for many different reasons. It would be nice if prusa included some kind of printed spacer to make that step foolproof.

    Again, assembly is straightforward. I took a span of 3 days to finish mine while dedicating a few hours each night to do it.

    Upgrades

    A couple of things can be improved on the printer. The printer isn't terribly noisy, but you can make it damn near silent with a few upgrades.

  • The vibration dampers mentioned previously (https://www.thingiverse.com/thing:1707045) work damn well to eliminate a lot of sound. I've also seen people claim that putting the printer on a concrete paver block and then putting that block on rubber feet eliminates most of the sound as well. (http://shop.prusa3d.com/forum/improvements-f14/best-usd7-buck-improvement-you-can-make-t3051.html)

  • After the vibration dampers, the hotend fan becomes the loudest thing about the printer. I ended up buying a 40mm Noctua fan and printing an adapter (https://grabcad.com/library/mk2_40mm_fan_duct-1) to mate it to the extruder assembly. Now the only thing I hear is linear bearing noise. Wiring in the noctua fan isn't plug and play though. I cut off the stock fan and crimped some dupont connectors on the leads and connected the wires that way. Soldering works too.

  • I don't care what you do, but find a new solution for a spool holder. The one prusa includes is terrible. Easiest solution is to print or use a pvc pipe to connect the two spool holder brackets. I went another route and printed a spool holder that used 608 skate bearings to make the spool holder buttery smooth. http://www.thingiverse.com/thing:1832235

  • The method to mount the y-axis bearing is not great. Print these out (http://www.thingiverse.com/thing:1819779) and switch out the zip ties when you get a chance. No rush to do these... just something to do when you want to tinker. Look up the igus drylin bearings too... a lot swear by them.

  • Also software. If you can swing the $150, I highly, highly, highly recommend simplify3d. Their slicing is second to none, and their support structures don't make a mess and require a ton of print cleanup.

I remember scrambling for those pesky m3 screws… getting the right length etc. I used to buy them at about $.25 each from the local “metric” carrying hardware store! Amazon has these assortments…

https://www.amazon.com/gp/product/B014ONCP88/

And 608 bearings! WTF is a 608 bearing? Again, Amazon comes through…

Get this or something similar: https://www.amazon.com/Hilitchi-210pcs-Stainless-Socket-Assortment/dp/B014ONCP88/

Theres a bunch of mods that require various sizes of m3 screws, having a variety pack around great.

I have a few boxes of misc nuts and bolts, which happen to include M3x20 (it's a fairly common size)
