Heat The Print Bed (without a heater) Attempt #2

thingiverse

This is an efficient alternative to the Printrbot Simple 1403 for use with E3Dv6 hot ends (might also be suitable for standard UBIS models).\nPrint edges curling and prints falling off the bed in low temperatures? While Singapore's sunny climate poses no issue, my own prints become unruly whenever someone turns on the air conditioner and sets the thermostat below 25C.\nThis simple yet effective deflector harnesses exhaust heat from the hot end, redirecting it onto the print bed. The result is a consistent 3 degree Celsius temperature increase, sufficient to maintain large prints in place while small ones remain firmly attached to the bed without the need for extensive upgrades.\nThe open design ensures that cool exhaust blows through, avoiding any potential bed contamination.\nPrint Settings\nRafts: Yes\nSupports: Yes\nNotes: I found success printing with a 2-layer raft, as it results in prints that are both tall and slender.
