Filament-Role-Holder

thingiverse

Hi! I need a spool holder that's super easy to use and allows me to quickly swap out materials. Also, it needs to fit in tight spaces because I often have to move my UM2 when changing filament. This spool holder is designed for all filament brands with widths less than 80 millimeters. The central hole should be at least 52 millimeters in diameter (compatible brands: REC; Verbatim; Ultimaker; Innofill; Colorfabb, and others). It has a ring on the front for feeding filament through. Here's why this design is awesome: 1. Filament won't jump off the spool. 2. The UM2 feeder requires filament from underneath. Here's how to assemble it: Put the spool holder on a flat surface, rotate the rack so that the ring for filament is on the left side, place the spool with the core on the rack, and thread the filament through the ring - ensuring it unwinds clockwise! Part dimensions: Length: 200.5 mm; Width: 100 mm; Height: 126.5 mm I want a solid part, so I used these settings: Top Solid and Bottom Layers: 7 Outline/Perimeter Shells: 3 Skirt: 2 lines only at the first layer; 4mm away from the part Minimal Infill Length: 1mm Printing Speed: 3300 mm/min - 55 mm/s Nozzle diameter: 0.4 mm Material: PLA (Brand: REC) Temp Nozzle: 215°C Temp Heatplate: 65°C If printing both parts at once: Retraction Vertical Lift (in Z+): 1.00 mm (if possible) Note: Printing in the first/last layers can cause the outer lines to slightly lift. It's better to print one part at a time. Printing time (both parts at once): 20h 25min (With: Nozzle diameter: 0.4mm / Layer 0.2mm / Top+Bottom Layers: 3 / Shells: 2 / Infill: 15% / 3500 mm/min = 58 mm/s --> you would need about 10h 50min) I think printing with a Nozzle 0.8mm will be faster...! P.S.: It works extremely well and the spool moves smoothly! (Tested on over 200 hours) At least: This is my first upload. So, I hope it works on your printer. If you have any questions or need further clarification - leave a message, and I'll respond as soon as possible. Happy printing! New Version / Thing files Now it's online (04.09.17)! With settings like the first version: ~13 hours 32min ~28m Material --> After that print, I can say: Aside from the fact that my print isn't perfect due to feeder issues and a slightly larger nozzlediameter, it works. Now, I've changed the nozzle and cleaned up the feeder. I'll be printing another one soon with better results!
