Did you know that if you subscribe to Adobe's Substance products, you have access to stock 3D models in their asset library https://substance3d.adobe.com/assets such as the base mesh I modified for this toaster? https://substance3d.adobe.com/assets/allassets/693b427d5bc3378b1fa0155da785c4b0761b9df6
Fair warning: All of the Adobe Substance assets I have previewed so far are unnecessarily high poly, so using them may require lots of optimization, however even just reusing the vertices at the extremities of a shape (the corners of a cube, for instance) can give you a huge head start.
(Quick tip: Flat faces on non-deforming meshes do not need subdivisions, and can usually be collapsed, such as on the front side of this toaster where I removed all the recessed buttons as shown below.)
(Another quick tip: Internal parts of props that are not meant to be viewed can also be removed to optimize a mesh, and even some of the details, such as the number of wire racks inside the toaster, can be reduced without noticably degrading a prop's appearance.)
