Sanding Drum for DIY drill/dremel

<b>CAUTION: Rotating Part, Use All Protective Measures. Do Not Use Ill Fitting Parts.</b> I've Constructed a Handheld Drill from a 12V DC Motor Featuring a 3.17mm Shaft. I Integrated a Micro Drill Chuck and Successfully Utilized It as a Precision Drill. The Combination Produces Good Torque but Relatively Low-Medium RPM. The Chuck Supports Drill Bits Ranging in Size from 0.3 to 4 Millimeters, a Range That's Difficult to Find in Affordable Drums of This Size in My Area. As a Result, I Designed and Fabricated My Own Drum. It Offers a Secure Fit for an M4 Bolt, Which Allows for Easy Assembly. If the Drum Does Not Permit the Passage of the Bolt Through Its Hole, a Gentle Sanding with a File Should Resolve the Issue. For the Shaft, I Employed a Partially Threaded Socket Head Bolt and Nut in M4 Size, Spanning 40 Millimeters. To Secure the Bolt in Place, Tighten the Nut at the Base. To Enhance Grip on the Drum, I Applied a Piece of Sandpaper Using Cynoacrylate Adhesive, Which Offers Rapid Bonding and Unparalleled Strength When Working with PLA Materials.
