As I am new to 3D printing, I decided to jump straight in with the kit. It took me a couple of days (10–20 hours) to finish building it, and I took my time to check and double-check each step. As well as this guide, the C1 build guide contains some great comments, and Ifti's video build guide on YouTube is excellent.
A couple of notes: 1) A screw organiser is by no means necessary, though it might speed up the build process. I spent most of the time gathering the right screws rather than actually building the thing. 2) A small magnetic hex driver, especially a 2.5 mm one, is very useful. Not only does it hold the screws in place, but I also found that it is much easier to apply the correct amount of torque with a handled driver than with the supplied hex key. 3) I received the old Core One kit with added Core One+ parts. This means that some items (e.g. the top vent and the nextruder vent thingy) might be duplicated (i.e. both the old and new versions). Be aware of this and use the correct parts. 4) Finding the right amount of torque can be tricky. I stripped the plastic threads on one or two screws, though not so much that they lost grip altogether. I also didn't use any threadlocker. So far, the build has held up with no loose screws (~100 hours of printing).
Overall, I found it a very straightforward and enjoyable build. Enjoy!
Have a look at the C1 build guide, it has more comments.
Contrary to what others say, a screw organiser isn't necessary. Just cut the lids off two or three of the smallest boxes in the kit (the kind with the Nextruder hotend in it) and neatly stack the screw bags in there. Sort them by type and size. Only cut off the top right corner of each bag and remove screws when the guide asks you to. This way, you end up with spares in labelled bags for later storage and you don't lose much time at all.
Never mentions install of the air filter, doesn't mention anything about the thermal pads needing installed, only has you place 4 rivets in the top panel (leaving 4 other empty holes and a loose top), many pieces were in different boxes from what the instructions say, and the guide for belt tensioning and alignment really should have came before enclosing the whole assembly. Im also done assembling and have an extra e1 3d printed part that no guide mentions. For the time it takes and the price, pretty sloppy
the core one guide has many more comments than this guide and is worth referring to during assembly of common parts https://help.prusa3d.com/guide/1-introduction_835490#860180
