There's a small chance for this list to change, especially the screws.
You can often find better deals at local stores.

15x5mm cylinder magnet4can be slightly thinner/thicker
magnet grade doesn't matter much

you may want to try weaker magnets as well in case these cause too much friction for some spools, so perhaps 15x2mm magnets that you can stack or unstack		https://amzn.to/3cxQosy (use 2 or 3 of these instead of a normal one)https://amzn.to/3wd0Pt6 (slightly thinner)https://amzn.to/3iyrCw2https://s.click.aliexpress.com/e/_A6LK1Zhttps://s.click.aliexpress.com/e/_ASiQ9v (these are the ones I ordered)

large panels2for large windows option only, 1-2mm thick transparent sheet
(PETG can be cut with scissors)
158x158mm with a corner cut out
Check local stores for better deals or laser cutting services		https://amzn.to/2SfM6zahttps://amzn.to/3pDI0gh (different sizes; A1 is cheaper for the size)https://amzn.to/3vbS418 or https://amzn.to/351Wxcl
12
small panels1 or 3one for back window, two more for small side windows if not using large windows,1-2mm thick, 124x70mm
there is an option without windows
13
filamentabout 750g for large windows version with recommended filament saving settings
I use Fiberlogy Vertigo filament, similar to Fillamentum Vertigo Grey (or other glitter dark gray filament). Makes a big difference vs plain filament
14
silica gel OR molecular sieve below100gmolecular sieve might be the better alternative for achieving very low humidity
you may want enough spare silica for at least 1-2 reloads
it should be at least 2mm to avoid it getting out through the slits
it often is smaller than advertised
1kg/2lbs container are usually cheaper		https://amzn.to/3cvq7Lbhttps://amzn.to/3vdvwwV choose orange or bluehttps://amzn.to/2TcBkcUhttps://amzn.to/3cy4EkO not in a container, or: https://amzn.to/3crTBcPhttps://amzn.to/3ivarLV
15
4A molecular sieveit's supposed to be better than silica gel at absorbing moisture
mine hasn't arrived yet to test
I ordered the 3-5mm size. Smaller could work		https://amzn.to/3v7gicX these look quite small but should workhttps://s.click.aliexpress.com/e/_Achxzd (this is the one I ordered)
16
W gasketoptional, for lid and hygrometer sealing, about 4mm wide. I use door sealing gasket in W shape (or I shape) from the hardware store, cut in half. Works better than TPU, but I could make TPU models for convenience. You might find some replacement.couldn't find anythinghttps://s.click.aliexpress.com/e/_9uFy8X select type I and favorite color. You'll have to cut it in half
17
P gasketfor the filament lock, 9mm wide. You only need a little bit. I use door sealing gasket in P shape. Or find a suitable replacement like the more common D shapehttps://amzn.to/3g6zhQK this is not it, should be a P shape, not a D shape, but it's the same dimensions and might still workhttps://s.click.aliexpress.com/e/_9uFy8X select type P and favorite color
18
double sided thick tape, or:for the windows. Only 6-8mm wide and has to be ~1mm thick and with the strongest adhesive. Tape is cleaner, silicone is faster to apply and can seal better.
19
silicone sealant or other adhesivefor the windows, alternative to the tape
20
3x4mm PTFE tubefor reverse Bowden to the printer so it doesn't pull the box or jerk the filament, and a small piece for inside the box to prevent rougher filament from getting stuck behing itself (not great English here, I know...)
larger 3mm or 2.5mm ID tubes have way less friction, but the 3mm one is pretty thin
some tubes are not slippery and cannot be used (some completely clear tubes are not good for example)
it tends to become less slippery after a while, so I buy more and replace it from time to time		https://amzn.to/3w8hsWZhttps://amzn.to/2RIP3I9https://amzn.to/3xhQcFNhttps://amzn.to/35aAfoAhttps://s.click.aliexpress.com/e/_Atv0Qj select 3x4 or 2.5x4https://s.click.aliexpress.com/e/_A07BUb select 3mm ID
21
(gaffer) cloth tape
or textile electrical tape		optional, for the rollers, to increase friction with the slippery spool so the rewind works better
also reduces noise, especially with textile tape or some other thick tape
look for the one that has visible cloth material
30mm wide would be ideal, but I haven't found any, so you'll have to cut it to size		https://amzn.to/3iEVtDk needs cutting to size
https://amzn.to/2RRAwtL needs cutting to size
https://amzn.to/3gA6e7f or https://amzn.to/35j9Y7U needs cutting to size
I'll be testing this one		https://amzn.to/3gurXx5 needs cutting to sizehttps://s.click.aliexpress.com/e/_AfHkQj needs cutting to size
