Plugs and Head Cover for the KISS Sidewinder Rebreather

thingiverse

The plugs will fit the loop / counterlung orifices on the scrubber bodies of the KISS Sidewinder. They will probably fit other KISS rebreather models like the Orca Spirit too, or in the case of the loop plug most KISS models. The O-ring grooves are designed to take the same size O-rings as the unit, making it easy to get the right size ones from a spares kit. Use the plugs to seal your scrubber airtight if you are storing the sorb between dives. Their ends are also designed to be slightly larger than the outside of the orifice, and thus can be used to protect the unit during travel. And they have little holes to make it possible to fit a string to hang them when not in use. If the scrubber is stored with the cell head removed to allow the cells to dry, you can use [this design](https://www.printables.com/model/58447-compression-scrubber-cap-for-kiss-spirit-and-sidew) to seal the top of the scrubber. The head cover is designed to fit over the cell side when transporting the sensor head separate from the unit, protecting the cell membranes. **Update:** I have updated the top and bottom plugs to use less material while still providing good stability. I have also added a version of the plugs with a vent hole, and a plug for the hole (should be printed in TPU). This allows you: - take the closed scrubbers and sensor head with the cover and vented plugs fitted onto flights, without the plugs popping out due to the decreased cabin pressure; - fit the hose from a flow meter into the vent hole, and use the vented top plug and the cover (or the scrubber container with the bottom plugged) to check the flow rate of the CMF orifice without disassembly of the LP hoses. **Update (3 Nov 2022):** I have added a head protector - this still covers the bottom of the sensor head, but has got big holes in it to allow airflow. It can be used to protect the head and in particular the exposed cell membranes while drying out the head after diving. I have also added a version of the top plug with two vent holes - this can be used to feed O2 through one hole for sensor calibration, while allowing excess gas to escape through the other hole.
