Then you should be fine.
On the first try (not perfect but usable) we were able to print carbon fiber reinforced nylon seal holders using a $200 Ender 3 V2 printer.
Made a cardboard enclosure, used a dehumidifier to get humidity down to 30% in the room and a heater to get it over 80 degrees, also used a filament heater.
