Hey, I just pulled apart a toaster that was in a vacuum seal, trying to figure out why it keeps burning the bread. Do you ever model mechanical parts in 3D to catch flaws before you build them?

Looks like the heating element’s winding got too close to the insulation board. The element’s over‑sizing the air channel, so hot spots form, the insulation melts, and the next slice gets a scorch. I’d run a quick finite‑difference thermal sweep with the exact geometry and check the temp rise over the 30‑second cycle. Then, if you still see 150 °C spots, tighten the clearance or add a heat‑sink bracket. That’s all I’ve got to say about this toaster.
