The Space has a selection of usable filament within sealed dessicant containers. This should keep the filament dry and usable, but when using this filament please return the small dessicant tube to the tub and then seal the lid.
Pay for filament used on the space tablet near the fridge, you can calculate the amount used with the software (But guesstimating is cool too, we trust you)
If you are leaving personal filament in the space write your name on it. The majority of space questions are ‘what is this weird filament’ and ‘can I use it’?.
Some filaments that are available in the space may not be marked with a type. Be cautious when using these and if you’ve got the skills to identify the material please note it on the spool, along with some recommended settings.
