Filament Spool - V1.1

thingiverse

I made this Filament Spool because I want to start extruding my own filament soon. So, I decided to create spools that I can use to store filament on. This spool is designed for about one kilogram of filament. It should work with any standard filament holder (yet to be confirmed). The spool was created in Design Spark Mechanical and I have added the original files so you may edit as you please. This project is a work in progress, so tell me if you have any problems, ideas, or suggestions. Print Settings Printer: Anet A8 (Prusa i3 Clone) Rafts: No Supports: Yes Resolution: 0.2 Infill: 20% Notes: The bottom needs supports everywhere, while the top doesn't need supports at all. Post-Printing Assembly and Instructions Find the two sets of holes near the base on the "bottom" piece and push the supports out of those holes. Then take the "bottom" piece and apply adhesive around the lip designed for the "top" piece to slide onto. Then slide the "top" piece onto the "bottom" piece, and then the spool is ready for use. To start rolling filament onto the tube, use heat to bend the filament at a 90-degree angle with the short side being about one-half inch or one centimeter long. Then insert the filament into the respective hole on the spool (smaller hole for 1.75 mm and larger hole for 3 mm). If you want, you can heat up the loose end of the filament once again and bend it to prevent it from falling out. Then you can start rolling the filament onto the spool. Happy Extruding! Change log V1.1 - Changed rotation of smaller polygons from sixty to forty-five degrees to improve overall aesthetics. - Added a double wall to the center of the filament holder to make it easier to use filament holders (prevents filament that you must "lock in" from interfering). (Future Plans) - Change to holes from polygon to a more custom shape in order to reduce filament usage and increase or maintain the same structural strength. - Edit the two-layer wall system to remove the covers that hide it to allow for easier insertion of filament into the holes. - Make three more versions that can hold one-half kilogram, two kilograms, and three kilograms of filament instead of just one kilogram of filament. - Make two versions of the spool. One with the two-layer wall system and one with only a single wall (for less filament use). - Design a way for the filament to be held in place once the spool is fully coiled.
