Better driveway reflectors

I've found that the regular fiberglass driveway reflectors that you can get at a big box store last for a season or two but then they become awful to touch (fiberglass in your skin) and are very fragile to being hit or bent.

So I designed this shape to sit on top of a 1/4" (6.35mm) steel rod that I painted and hold these reflective stickers.

Available on Printables.

Yofi Blog

Hello and welcome to the Year of Invention Blog. It's my intention to use this blog as a simple place to document projects, what I learn, what tools and processes I used, and what I'd do differently next time. Once started, I hope the blog continues to document my creative projects reasonably indefinitely, using very loose definitions of "invention" and "year."

Turbo-charging a manual coffee grinder

Porlex Mini Grinder Okay, okay, I don't mind the morning ritual of hand grinding coffee beans in a manual, crank grinder, BUT when you've got guests and you're trying to make 4 or more cups of coffee, the quaint hand crank process can become a tedious chore for someone with their pre-coffee anger. So, I had the idea to use my old drill and a 3D-printed drill adapter to drive it super fast. Adapter in loco This was my first time using CAD and a 3D printer in years and was great starter project. It took a couple tries (first started with just 1/4" hex shank, but fattened it up to 3/8". I also learned the importance of perimeters and infill and bumped those up to 8 and 100%. Fusion 360 and STL files are available on Printables .

Groundhog Trophy

You can't have a groundhog party without a groundhog trophy. I modelled this in Blender based on the techniques of this tutorial . The one thing I learned was to not subdivide only parts of the mesh. It results in areas with faces with more than four vertices which then cannot be automatically subdivided, so next time I would always subdivide the whole mesh rather than in-parts.
