Hot water bottle stopper
thingiverse
A Simple Stopper for Common Hot Water Bottles. I'd love to see someone with OpenSCAD expertise create a parametric remix of this design. Unfortunately, I don't possess the necessary skills. This particular stopper features a M24*4 thread, but it can be easily customized to fit your hot water bottle by editing the dimensions in SolidWorks (thread feature requires 2016+). I would not recommend using low-temperature materials for this project, however, a four-walled PLA part with ten bottom layers has survived so far without any issues.
