Want some advice on which filaments to use (lemmy.world)

New to 3D printing (my printer didn't even arrive yet) but I have a few projects I want to start with and I am unsure of the correct or best materials to use for them.

So here are three things I want to print for sure:

  1. Adjustable leg for IKEA BROR. This BROR rack already has a ton of stuff on it, likely in the 20 - 30 KG range so it would need to be a material that can stand that weight. It's also a garage so the expected temperature range is something like 30 to -5C
  2. Some counter top containers to hold things. One of the things I want to hold are laundry detergents. These can be a bit heavy and some detergent can spill, not sure if this can react with the plastic. Indoor use only so the temp range is like 25 to 20C.
  3. Mount plate for a post cap light. I will be screwing these into the post and then the light will lock on to them. The post cap light itself is pretty light however it needs to be able to withstand the elements (snow, rain) and also animals like raccoons and squirrels that might try to pry them off. Temp. range is like 30C to -30C.

If anyone has any suggestions please let me know!

Store filament in a big plastic tub with a kg of colour change silica. But yes a filament dryer is a good investment too. Just a single roll one will do.

Is that better than vacuum sealing them? Vacuum sealers are pretty cheap IIRC.

Your best hope for storage is it not getting much wetter, ziploc bags with silica are fine, a tub is easier to paw through and grab what you need quickly.

A drier will actually refresh a roll and get it printing close to new again. Look for excess stringing for the early signs, and the filament bubbling and/or popping as it comes out of the nozzle for extreme signs of wetness.

I'm in a fairly dry environment, I'll happily leave a roll on the printer for a week without adverse effects. But always store an opened roll off the printer in the tub. 3d printer filament storage

Dry and then store in sealed container with silica gel. Silica will maintain dryness, but will not dry filament by itself.

Also, containers must have a seal of some kind. Regular plastic tubs will let some moisture in. For a few days or a couple of weeks that'll be fine, but over a month they'll let moisture in. Get vacuum bags.

There are pretty cheap reusable vacuum bags that use a little pump. I use a cheap kitchen vacuum machine, and regular food storage vacuum bags.
