An Entertaining Toy-Arm That Fires Rubber Bands At Your Desired Rate. You Can Quickly Swap Out Barrels And A Single Clip Can Hold Up To 72 Rubber Bands. Plus, "T-800" Is Written On The Side, Making It Look Even Cooler. Here's A Video Of Me Shooting Some Rubber Bands With A Prototype Version Of The Toy: https://www.youtube.com/watch?v=NmIA7zunx6I To Use The Toy, You Need To Attach A Small Rope Or String To The Barrel And Make A Loop Around It. Then, You'll Want To Stretch Out The Rubber Bands As Far As Possible And Repeat The Process Until There Are No More Rubber Bands Left. Finally, Attach The Other End Of The String To The Trigger. Print Settings: Rafts: Yes Supports: Yes Resolution: Doesn't Matter Post-Printing: Once You've Printed The Pieces, Simply Assemble Them Together Like Shown In The First Image. Custom Section: Project Name: Elastic Minigun Overview & Background: In This Project, We'll Be Mixing 3D Design With One Of Your Favorite Activities. Me And My Friends Often Play Airsoft And Nerf Wars On Weekends, But Also Rubber Band Shooting At School. I Decided To Combine Our Fun Times By Creating A Rubber Band Minigun For Weekend Activities. Objectives: With Your Help, I'll Keep Upgrading The Model Until It Has No Technical Issues. I'm Open To Your Ideas And Would Love To Work Together. You'll Also Learn About Plane Surfaces And Flow Modeling By Opening The .ipt Files I've Provided. Audiences: People Who Understand My Drawings Only Need Basic Knowledge Of Autodesk Inventor, Equivalent To 100 Hours Of Experience. For This Project, I Used The 2016 Version Of Inventor, So Make Sure You Have The Same Version Installed. Subjects: This Project Is Relevant In Math And Physics Classes. Skills Learned: By Viewing My Parts, You'll Learn A Lot About Plane Surfaces And Flow Modeling When You Open The .ipt Files I've Provided. Lesson/Activity: Since I Already Designed The Whole Thing, All You Need To Do Is Download The .stl Files And Print Them. If Your Rubber Bands Are Wider Than 2 Centimeters, Download The .ipt File For The Barrel And Extend The First Extrusion's Length To Fit Your Rubber Band's Size. P.S.: Make Sure To Stretch Out The Rubber Bands Until They're Close To Breaking Point! Duration: The Time It Takes To Complete A Project Like This Is About Two Hours If You Know What You're Doing. With Brainstorming And Mistakes, It Might Take Around 20 Consecutive Hours. Preparation: Autodesk Inventor Has An Intuitive Interface Where The Level Of Experience Needed For Each Task Is Clearly Indicated. The More Left-Handed Options Are Easier To Use, While Right-Handed Options Are More Challenging. References: To Optimize Your Machine's Power, Research The Maximal Length Of Your Rubber Bands On The Web To Minimize Mistakes. Rubric & Assessment: A Passing Student Will Have Created A Functioning Barrel That Can Shoot At Least One Rubber Band Per Second. Students With Higher Grades Will Have Designed A Support For The Barrel, And Top-Tier Students Will Have Added A Trigger To Pull The String, Held By The Support
