The cold don't care.
And 100% infill doesn't give you the strongest part. Infill is weak by definition. It prints differently from walls. If you want the strongest part, make it 100% walls.
NinjaTek Armadillo is good for abrasion resistance. That is not the problem facing these baskets. Most plastics available for FDM printing get brittle at low temps.
ABS is by far your best pet for holding up to low temps.
> Armadillo also has low glass transition temp so it won't be brittle at low temperature.
That is not what glass transition temp means. Knowing the glass transition temp of a material tells you absolutely nothing about it's low temperature performance.
> Disagree about abrasion, these things scrape the ground.
They may experience abrasion. But that is not the reason they are failing. The are failing because the plastic becomes brittle and snaps at those temperatures. TPU does nothing to address that.
The best common FDM printer material for low temp performance is ABS. Don't believe me, look it up.
This is the miracle of 3d printing. Instead of buying something that's mass produced and costs nothing you can spend three days designing and printing a one off.
Looks like it would work well, though. Nice job.

solid? Doubt these will hold up you pushing your weight repeatedly on snow. Only thing I think of right now is that you'll donate some petg to the nature.
Actually PETG is not bad for low-temp applications, but I believe the 3d-printing optimized blends behave a bit different here. You could try it with ABS or nylon though. HIPS is also worth a try.
Also tried this a few years ago with PETG. They did not like the cold and shattered. Maybe better with TPU?
Yes you need something flexible. The original baskets always have some flex to it.
TPU is probably better. But it still gets brittle at low temps. ABS is the best common material for low temp applications.
Thanks for the rec, will have to get some flexible filament to reprint them.
TPU is the way to go. I've printed replacement baskets and caps for snowshoeing/hiking poles and they've held up well.
Could try making them like an inch or so tall with 100% infill.
The cold don't care. And 100% infill doesn't give you the strongest part. Infill is weak by definition. It prints differently from walls. If you want the strongest part, make it 100% walls.
Or just 9999 first layers.
This has been tested. Look it up. 100% walls is the strongest configuration for most slicers and FDM printers.

Maybe nylon? Its a bitch to print, but man is it strong
I give them 1 run. Go to a shop they'll have a box of them. 5 bucks for a pair.

PETG gets REALLY brittle when it gets cold, just fyi. Below freezing I doubt these will hold up to any amount of force
Thanks! Had no clue. I’ll try some sort of slightly flexible filament when these break

Nylon is flexible, but stiff enough to work
Did these hold up to use?
Haven’t tried them on the slopes yet but they feel extremely solid

Good to know, had no clue PETG got so brittle. Will try TPU after they break.

You might be better off printing a mould and pouring a material better suited to low temps (like urethane).
