About this 3D model

Secretly broke my wife's hair remover sticky roller and printed a new one for her, showing that I am a capable man. The size of the hair roller is 15.7cm x 12.2 x 8.5cm, fits with 10cm long sticky paper roller，if you don't have a paper roller, you can print the test roller or the roller seal instead, just for fun. ------------------------------------------------------------------------------------------------------ Printing settings: PETG and PLA+ are recommend, because it needs to be opened a little to install the roller, there’s a risk of PLA being broken. Infill Density - 15% Layer height - 0.2mm Only the two small columns in the pic below need support.
