What should I get to prepare for owning my first 3D printer?
I'm fairly new to 3D printing, having borrowed a spare printer from a friend for the last few months. I'm looking to buy myself something that's more reliable because it's a rudimentary i3-alike that requires manual bed and arm levelling between most prints, clogs while printing 75% of the time and has an annoying 4cm X offset that seemingly cannot be corrected by software or firmware adjustment.
My friend exclusively works in ABS so that's what I've got at the moment. I'll probably be doing a lot of work in ABS as durability and long-term outside weather resilience will be important for most of what I'm making.
What would experienced users suggest I obtain/do first, to avoid later hassle getting things I've not considered, or fixing things that can be prevented from breaking if tackled early? From a little bit of browsing this board, reading the manual and watching the start-up guide video on Youtube, I'm thinking the minimum I would need in addition to the Prusa i3 MK3S kit is:
- A spool of PLA to do first layer calibration after assembly (Or can other materials can be used for this?)
- Spools of black and orange Prusament PETG, so I can immediately print the latest upgrades. I understand currently the R4 extruder housing melts easily and the retail kits don't yet ship with the R5. Or is it best to get a third party to print me a new extruder casing in a material that the extruder can't melt?
- Possibly some sort of silicone sock for the hotend, tied on with fine wire? I don't have any experience with them.
- A bottle of isopropyl alcohol for bed cleaning (the bed on the printer I've got at the moment is glass and uses ABS/acetone for adhesion which I understand isn't suitable on the MK3S plates because it degrades the PEI adhesion coating)
- SD card reader adapter for my PC (Currently using Pronterface on a laptop over USB due to the temperamental printer)
- Eventually, an enclosure for ABS printing (The Lack table conversion looks fairly practical)
Any advice would be gratefully received.

In fact, the list is quite good. For beginning you will get spool of PLA with the kit. Start with it, calibrate, try couple of prints.
PETG for spare parts, I think black should be enough. Orange parts are rarely being changed or damaged. If you have some friend to print you new parts, fine. I think you can live with the ones coming with kit and print the new onse as a spares later yourself. I am running the R4 parts for more then year, no problem with (ok, the extruder cover is a bit melted in one place).
Depends a lot on what you are about to print. You mentioned mostly ABS. I print ABS very rerely. It has too much negatives for me and there is always some other alternative. Mostly I am fine with PETG for more durable parts (also with carbon fibers), PLA for the things to be nice 🙂 Therefor melting of printer parts is not much visible. Printing ABS could be a bit different. Prusa now comes with ASA, maybe it would be a better choice for you.
Enclosure, yes, for ABS. Otherwise for the beginning waste of time and money. I did it, it is nice, I made a lot of mods in the electronics of the box but mostly I print with open doors. At least it saves the printer from dust 😉
IPA is a must, try to buy 99% or as much as possible. Not everywhere this is available. I could buy in my country a liter of 99% for 4$.
Buying a printer, you can choose what type of steel sheet you want, smooth PEI or poweder-coated. I recommend both. Poweder-coated is great, but sometimes man needs a smooth bottom of the print.
Start with SD card, but then I would recommend using Octoprint on Raspberry PI. I do not have the small one integrated with the board, I have the normal one placed externaly. No issues with it.

I've put together a list here that includes a recommended "nozzle clog first aid kit" for the inevitable plug. Note that acetone is only recommended for the smooth PEI surface, and even then infrequently. The powder-coated sheet should not need anything more than 91%+ isopropyl alcohol (at least in theory) though I've had to do more to get mine working semi-reliably with PLA.

Dawn dish detergent for cleaning the bed. Rolls of unscented/non-moisturized paper towels for cleaning the sheets.
Alcohol at 91% or higher concentration; some rubber gloves to keep oils on you fingers when you use the alcohol. If you plan for cleaning with alcohol, buy it in gallons.
I probably won't buy the e3D-V6 Pro Sock again, it deteriorates too fast when printing infill that curls. Instead buy the non-Pro version that doesn't cover the nozzle down to the tip - so curl snags don't destroy it. Your experience may vary.
A tube of #2 white Lithium Grease or Superlube to pack the linear bearings before installation.
ABS stinks ... and produces noxious and toxic fumes. Any enclosure must be negative pressure and vented out side. Recirculating VOC removing air filters are too expensive for home use. Though many have made homemade types using face mask VOC filters, they have a very short lifespan and will be expensive to operate since each print will need a replacement cartridge if you follow the filter mfg instructions. If you vent outdoors, keep the flow volume low - you only need a couple CFM to adequately vent the fumes from a LACK - low exhaust volume also save heating and cooling costs and makes maintaining enclosure temperature a lot easier.
Windex for prepping the bed for PETG. It is a good release agent that helps keep the PETG from welding to the PEI.
Think about something to cool the extruder motor when printing inside an enclosure. Many reports of the higher temps causing filament handling issues, especially with lower temp materials. Passive heat sinks work, and there are nice looking fan and shroud designs.
I good small metric tool set.
And if you plan on printing a lot, order an extra set of bearings, especially if you don't pack them with grease before install.
RE: What should I get to prepare for owning my first 3D printer?
Get yourself nickel plated copper nozzles if printing PETG, but current best nozzle is reputedly Tungsten Carbide, not to be mixed up with Tungsten alloy, but still quite rare.
Normal people believe that if it ainât broke, donât fix it. Engineers believe that if it ainât broke, it doesnât have enough features yet.

if you haven't ordered yet, getting the printer with the textured build plate and ordering the smooth stickered build plate as an extra saves you about £10.pp or similar money units where ever you live

Two hot end cleaning items:
Automotive inspection mirror with a light. Beats trying to get your head under the extruder to see the nozzle.
Stiff brass brush. A good one stays clean and works wonders at removing heated filament. A bad one sticks to filament and becomes a sticky mess.
RE: What should I get to prepare for owning my first 3D printer?
If you find the enclosure noisy, consider mounting the printer on a paver.
