Venturi Filament Dryer P1S/X1C

The goal of this model was to be able to print a filament dryer that works well enough to replace the need to buy a separate dryer while meeting the following criteria:

• Holds standard spool sizes
• Has air circulation without excessive heat loss using the aux fan as the air flow source
• Uses heated bed as heat source
• can be run in conjunction with chamber fan to avoid heat soaking sensitive printer components

I also got inspiration from the following creator for the venturi nozzle used in this model so posting below in order to give credit!

Please make sure to print in a higher temp material than PLA, i have used PETG, with PLA as the support interface material in my print profile and have not had much warping on the parts even up to extended use on 100-degree bed temps.

I recommend testing your aux fan settings for each temp and adjusting as needed, may be useful to use a temp monitor/temp probe to really dial them in for low temp filaments like PLA!

IF USING HIGH BED TEMPS PLEASE MAKE SURE YOU SET CHAMBER FAN TO MINIMUM 20% TO NOT HEAT SOAK YOUR PRINTER
