I am looking for a few supplies of 3D printing filament, had been using Maker Geek, just found out recently they are gone.
I get my filament from https://www.filacube.com/collections/1-75mm-1kg-filacube-3d-printer-pla-2-filament-18-colors. Their filament works extremely well with my CR-10 printer.
I've had good luck with Prusament filament from Prusa in Czechoslovakia. They are not in the US obviously but their PLA and PETG filaments have been working well for me and I can usually get an order in less than a week, depending on availability. Shipping amounts to $4-5 per roll if you order 6+ rolls, which hasn't been a problem for me so far. I try to stay away from the Amazon sellers as their prices seem to be a bit on the high side.
