What is Project Redesign?
Project Redesign is an assignment that our class has to redesign something that is currently being used for our school. One semester, students redesigned a bench for the Innovation Center. This semester, my class is redesigning a tool holder for the woods lab. The holder would have mallets, hammers, wrenches, chisels, pliers or screwdrivers. I'm choosing screwdrivers and I need to make something to hold 16 of them. My project will have 2 modules to hold 8 screwdrivers and my design is competing against other students for extra credit.
Pre-sketch/Pre-search for design 1
My first design had the ability to hold 4 screwdrivers, so I would need 4 of these to be able to hold all 16. In this design, I overexaggerated the amount of space I'd need between the screwdrivers so they would fit.
V1 walk through
These are the sketches in Inventor pre-extrusion for the V1 design of my project.
This is the V1 design being extruded and then filleted.
Here is my design getting ready to be printed and in progress of being printed.
Here is my first design, it stayed on the wall well and held 4 screwdrivers securely and spaced out on the wall. For the next design, I decided to make the screwdrivers closer together and increase the radius of the circles where the screwdrivers are placed. I also decided to add another row of holders so the design could hold 8 screwdrivers instead of 4.

V2 design pre-sketch
V2 Walkthrough
Here are the sketches of the V2 design. (The holes in the drawing are smaller than they actually are.)
Here is V2 done and in the process of it being printed.
When I printed the V2 design, I didn't correctly set the design to the right side for printing. This caused the French Cleat to be all cut off and destroyed. The next time I printed it on the right side, which led it to being printed correctly. The thing I noticed was that I didn't correctly make the French Cleat to the right angle which should have been 45° but instead I had it at 50°. Even still the holder would be very tippy, so the final design would have to have a clamp at the bottom of the holder to clamp on to the French Cleat. Otherwise the holder was able to hold 8 screwdrivers together in it, spaced out plenty without issues aside from the tipping issue when I put them in.
V3 (final) pre-sketch
V3 (final) Walkthrough
Here are the pictures of the sketch before extrusion and what it looks like at a side view extruded and filleted.
Here are the pictures of the finished final design in Inventor and real life. Although the 3D print didn't come out as it should have, it still stayed on the French Cleat very well, sturdy, and held the screwdrivers how it should.
Reflection
I learned a lot during this project. I was able to practice my skills in Inventor and also learned about new tools in the program. I learned how to correctly measure the French Cleat and compensate for mishaps in the 3D printers. I learned how to use MakerBot and put the 3D prints in MakerBot the correct way to orientate them so they print the best. I learned more about the design process through trial and error. This project was a great start to this semester.
