Stove Knob Bump Gaurd

Oven got bumped into and the stove turned on. Thought it was a fluke and moved on. After the second time, I made these. Pull the tab at the top and they work normally, push them down and the knobs can't be turned.

Ignore the awful print quality, I decided not to waste filament reprinting since I'd never see it anyway. Very simple print, no brim or support required. PETG recommended since this area will get warm when the oven is on. 

Design is specifically for an electric LG Oven with glasstop stove. STEP file added, adjust as needed or message me with specs and I will adjust it for other stoves; if it can prevent a fire I'm happy to help!
