This print is mainly for SLA printers (with relatively large build volume) because this design needs printers with pinpoint accuracy for a watertight seal. Print out the different parts and secure them together with a 3d pen or a hot glue gun. Make sure the seal is tight!
This design is based on the Japanese toilet seat that cleans your backside. This can help the environment by using less toilet paper. Feel free to remix with the design and make it FDM compatible. I will upload another design with a syringe needed that will most likely be able to be printed on an FDM printer.
