Recycled water gun

Printing & Assembly Print both parts — PETG is recommended for better durability and water resistance. Add a 20 mm O-ring to the part that slides inside the main body. Insert the part into the body and assemble the water gun. Screw your water bottle into place, fill it with water, and you should be ready to go! 💦 Watertightness Depending on your printer tolerances, a little adjustment may be required to get a good seal. If you notice any leakage around the connections, simply add a few layers of PTFE/thread-seal tape until the connection is watertight.
