Our shelf is close to collapse and I'm determined that I can save it using my engineering skills and knowledge of 3D Printing. I purchased my Prusa mk2s 3D printer in 2017 and it is still going strong. I mostly print parts that I design that solve a problem.
This shelf was installed by the previous homeowners and it was simply too short for the bracket that was supplied. I took some measurements of the shelf profile as well as the distance from the end of the shelf to the wall.
MODELING THE BRACKET
I brought those measurements into Fusion 360 and began with a simple sketch that became the framework of the shelf bracket. Fusion 360 has many features but I mostly focus on the sketching and modeling aspects of it. It's easy to create a sketch. And once you have a sketch, extruding it into an object involves a couple of clicks. Extruding means you are using a sketch profile and converting into a solid object. This object is typically the foundation for the final design.
Once you have the basic part modeled you can build off of it by modifying the faces or creating new sketching on the sides of the object. Those sketches can be used to extrude to build onto the part or even punch holes through the object. You can even slice an object with a line or a complex shape.
This was an iterative process, where I started with a sketch, created an object, and began modifying that object with subsequent sketches or direction object manipulation. And after a few minutes I created a shelf bracket. Then that bracket would have sharp edges so I used filets to not only make the transitions from one plane to another smoother but also adds more material for strength for inside corners.
Tools and Materials Used:
Oveture PETG Filament - amzn.to/4nlJbON
Magigoo - amzn.to/40pL7Mi
Craftsman Screwdriver Set - amzn.to/4emzg7u
Hillman Anchors - amzn.to/4nqPXTG
No. 8 - 1 1/2 Inch Screws - amzn.to/4nlJCsp
Prusa 3D Printer - amzn.to/4elRMNr
BRACKET INSTALLATION
The shelf was quite heave with everyth8ing that was already resting on it. I pushed the bracket into place and had to hold it steady while I marked each hole where an anchor would be installed. Using my RIDGID drill, I drilled a 3/16-inch hole at each mark. Then, I hammered in an anchor in all four holes. I noticed as I hammered the anchor would bend, so I used lighter taps and that worked. As you can see in the video, I positioned the bracket in alignment with the anchors and installed each screw using my Craftsman screwdriver. I really love these screwdrivers, which is why I bought 10 packs of them. I tend to always misplace my No. 2 Phillips screwdrivers.
