Wanhao/PowerSpec/MonoPrice i3 Plus bed wire bushing

thingiverse

I found that my heated bed's wires weren't properly secured, allowing the negative wire to scrape against the metal undercarriage due to friction. After investigating further, I discovered that this issue could be easily resolved by inserting a bushing into the square hole with just a bit of force. This simple fix provides a softer surface for the wire to rub against, eliminating any potential damage or discomfort.
