AFUNTA 12 PCS 12V 40W 620 Ceramic Cartridge Heater and NTC Thermistor 100K 3950 Fit 3D Printer & Heat High Temperature Resistant Adhesive Polyimide Tape for Electric Task - Red & White

I dont know why I needed 10 of each but I got em in 2 days and one of em is getting the job done on my homemade filament puller that recycles plastic soda bottles into PET filament to 3D Print with. This is great especially since the price of a roll of filament went up 3 dollars in the last month and I certinly cant afford that along with the price of gas in CALIFORNIA $6.50 a gallon and food prices. So Ive saved myself a bunch o money reusing coke bottles

I was getting wrong readings with my hardware until I reprogrammed it for a 10k thermistor instead of a 100k. and replaced the 100k resistor with a 10k. If you are not aware of this then you will most likely overheat or under heat your parts.
