The article contains information about cases, holders/stands, 3D-models, and supplies for the Pinecil soldering iron. This is a small set of examples based on the many questions asked every week in the live Pinecil chat channel. There may be better althernatives depending on your part of the world, but this gives an idea of some possible options.
Aluminum hard case w/foam (check size before ordering if multiple listed).
Soft Bag Molle IFAK/EDC: look for bags that can fully open like a sandwich when unzipped which allows tools to be easily seen and retrieved. Bags that only partially unzip make it harder to find tools without dumping out the whole bag.

Brass w/Rosin - Brass Wool with hard rosin in the bottom for tip cleaning. Twirl the tip in the brass wool often during soldering to keep the tip clean. Lower the temperature and dip lower into the hard rosin when you need a deeper cleaning.
ESD Tweezers with case, budget set.
Flux NC-559-V3 from amtechdirect comes in a paste or syringe. There is a lot of fake Amtech online. Amtech is made in the USA and sold by 2 different companies. Many reports of cheap Aliexpress fake fluxes that simply do not work, ymmv.
Flux Relife RL-422-IM Halogen-free, low cost alternative.
Flux syringe Chip Quik SMD291
Solder Wick, variety pack: helps remove solder. First add flux to the area and also to the solder wick itself to add in removal of old solder.
Weller Lead-Free Solder here: sample of 3 common useful sizes (0.3mm,0.5mm,0.8mm), handy for small carry case.
Solder: first decide if you want to use No-lead or leaded. Leaded is easier to work with at lower temperatures. No-lead is used now by all manufacturers of electronics per ROHS. Depending on the work being done different sizes might be needed, for example, 0.3mm for small work, 0.5mm for pins, and larger 0.8mm+ for thicker wires. One could make due with smaller solder by folding a piece in half and twisting it to make it thicker. See the video below to help compare types.
Videos comparing expensive and budget flux and solder (includes links to items).
Fume Fan: this removes flux smoke from the air. Work near an open window and soldering outside also helps. Set up a work area where the air and smoke is being sucked away. Many videos showing how to make a fume fan for soldering.
