Hollow filament spool with DVD's for M3D / Micro 3D printer (made with 2 CD/DVD)

Work In Progress! Those Who Own an M3D (I Have One, But It's Currently Unavailable, Will Be Returned For Repairs) May Encounter a Problem - They Want to Use Their Own or Someone Else's Filament, Rather Than the Stock M3D Option. No Big Deal, But If They Plan to Utilize It Within the Internal Compartment Beneath the Print Bed, They'll Soon Discover That Spools Are Tough to Come By Without Purchasing Directly From M3D LLC. The Simple Solution is to Create Your Own! The Diameter of Those Spools Measures 120mm. I Wonder Where I've Seen This Exact Size and Shape Before... Ah Yes, CDs and DVDs - The Same Diameter! I Quickly Whip Up a Customized Spool Core by Attaching a CD on Both Ends, Securing It with Some Glue. Here Are the Features I Tried to Incorporate: 1) Ample Space to Affix the Central Core to the CD's Rim, Which Measures 0.5cm. 2) Filament Sizes of 1.75mm (M3D Diameter) and 3.0mm Each Get 4 Holes to Kickstart the Winding Process. 3) I Wanted a Design That Could Be Printed Using Minimal Filament, Yet Be Rock-Sturdy - Hence, 2mm Walls and a Multi-Stage Design. 4) Due to PLA's Tendency to Break If Wrapped Too Tightly, I Aimed for a Minimum Winding Diameter of 40mm. Print Settings * Printer: M3D * Rafts: Irrelevant (Don't Bother) * Supports: Yes - Only Needed from the Build Plate Upward. * Resolution: Low. 0.2mm Does the Trick. * Infill: Not Required * Notes: The Internal Compartment Requires No Supports
