This is one I just finished. A 4 sheet hanger tank with thermometer compartment for submerged glass thermometer. Holds 4 hangers and takes approx 725ml of chemical, although you should verify that volume with your own hangers. The tank can also be printer on Ender 3, v1 (the early Ender 3), because I tried it. Here are the specs for larger printers: PLA, 35% infill, 210C nozzle temp, 60C bed temp, no support, no brim or raft. Maximum speed 200mm/sec, .4mm nozzle. Approx time, 21 hours. Ender 3 special instructions: Turn tank on print bed as per photo to print long way forward and back. (all printers) Be absolutely sure the printer is correctly adjusted, including tire tensions. No wobble or slop in all mechanisms. Level bed carefully with 20lb bond paper. Pre-heat the bed to 60C for 20 mins before printing. Nozle, 210C, no support, skirt, brim, or raft. Even though PLA is pretty good about not pulling up from bed, this tank is absolute full bed size. Use glue stick on bed on the long ends of the tank. Print time approx 37h ours, shield printer from drafts. Failure to follow these instructions will likely result in bottom of tank pulling up on the ends.
