The side walls are 2 mm thick and the bottom is 2.5 mm thick. It’s rigid enough. I made it out of matte PETG; no support is needed. It turned out well considering that the material used is inexpensive and I struggled to find the right settings to get an acceptable result. For matte filament, using light-colored materials highlights the floral patterns; I used a dark color, which hides the details. Regular glossy PETG is more suitable for this type of project.   The model weighs 260 grams and measures 143x186x197.5 mm; it took my printer nearly 6 hours to print. I may make more models like this, if only to really solidify my design skills.
