Parametric MasterSpool with thread

thingiverse

Hello, I'm using a Prusa i3 MK3 3D-Printer and refill filament from http://www.dasfilament.de. The refill filaments save plastic and shipping weight/costs. To use it, I will need a master-spool that meets my requirements. I found several, but none met my needs, such as customizing the rod hole diameter or using less material and printing time. So I decided to make my own thing, starting with https://www.thingiverse.com/thing:1782398. My design is fully reconfigurable using openscad (http://www.openscad.org), so it's usable not only as a master-spool without needing glue. You can change anything for your needs and make a remix of it. I hope it's useful for everyone. Please give me a comment if you have some questions, remarks, suggestion or issues. I wish you happy printing. 09/24/18 Some small improvements made: 1. Additional text on the flange of Part B, 2. Better visibility in the OpenScad CSG compiler (fast preview), 3. Fixed some older little bugs. Note: If you are using OpenScad for customizing, find the path to the library file "threads.scad" and complete the path in the file "parametric_master-spool_with_thread.scad", otherwise you will get an error while compiling because the file cannot be found.
