10 Useful 3D Prints for Everyone

Light Switch Lock (Light Switch Lock by galactic | Download free STL model | Printables.com)

It seems like every house has one - the light switch that shall not be touched. Usually, the switch has no obvious effect, but whether it disconnects an outlet or even turns on a light in a completely different room, it can be frustrating to discover that it was flipped who-knows-how-long ago. Luckily, this print is here to help you set it and forget it, fixing your switch in the correct position. Even better, the switch isn’t fully locked in place, so it can still be flicked, albeit with a little more effort, in case you ever do actually need to (even though you won’t).

Stove Knob Lock (Mabe Stove Knob Lock by ebobadillamtz - Thingiverse)

Stove Knob Lock

For those with young children in the house, this print is a great safety upgrade for your stove. These days, most electric stoves come equipped with a ‘lock out’ function, specifically to prevent little ones (or particularly mischievous pets) from turning on the heat when you’re not looking. But it can be annoying to remember this every time, and gas stoves typically lack this feature entirely. Thus, the appeal of an easy, automatic knob lock is obvious.

With several sizes to choose from, these 3D printed buckles are ready to replace the broken backpack or luggage strap you haven’t gotten around to fixing just yet. Just fire up the printer and bust out the sewing kit!
