Eheim Jager 50W Aquarium Heater Water Jug Adjustable Mount.

I get pre-conditioned 5 gallon water jugs refilled at our local Fish store for water changes and needed to heat before changes so as not to be to cold. I had this heater laying around so I decided to create an adjustable jug mount since this heater is not a fully submersible one. You can adjust the depth into the jug depending on the water level when needed to heat. I used PRUSA PETG. I had to split the heater holder in two to accommodate my Prusa print height. You do not need both halves depending on jug depth.
