About this 3D model
I designed a thermometer holder with magnets for my p1s. No screws are needed, just 20 magnets (4x2mm). I recommend to print the inner side with petg or abs because of the temperatures inside the printer, the outside i printed with PLA. For assembling you need this magnets and thermometer (or similar) https://amzn.to/47540op (affiliate link) https://amzn.to/3vfr06N (affiliate link) If you have questions, ask them in the comments. Please tell me if you notice things which i should optimize. Happy printing!
