If you appreciate the time and effort I' put into designign my models, you can now show your appreciation by buying me a coffee on my link above. I am a STEM teacher of basic 3D design and introduction into 3D printing for kids here in Hong Kong. My uploads are a mix of stuff for the kids in my local area, hobbies I am interested in, stuff for my wife, our home and any other odd random requests I get. If you want to sell my designs send me a message for a link.
