Screw caps for different disinfectants

thingiverse

Because of the scarcity of disinfectants, many companies refill their bottles with homemade disinfectant solutions. I was approached by a fire department in Germany, which asked me to design spare caps for their used bottles so they could be refilled. I obliged, creating spare caps for every manufacturer and size that I could obtain. Two versions of each cap are available: one is a simple screw top, which can be printed using PLA or preferably PETG. The other features a hinged lid, requiring TPU/TPE to print effectively. To ensure optimal printing results, I carefully optimized these designs. Testing confirmed that they all fit snugly in place. If any issues arise, please don't hesitate to reach out to me.
