Filament Carousel
Description
Richard Horn from RichRap came up with the idea of the #MasterSpool. It is an great approach to safe resources and shipping costs. I took the idea one step further by making the master spool obsolete too. This #FilamentCarousel is capable of extracting the filament refill coils directly from the bag. A short cut in the centre of the coil is enough. The filament can stay in its package where it is protected from dust and to a degree also from moisture. Silica gel bags can remain in the bag to. For storage a strip of painters tape seal the package and locks the end in place. The coil on the carousel is able to spin freely. So the filament doesn't wind up. The movement of the print head induces permanent random rotation of the coil, witch prevents the filament from jamming inside the bag. See also my [concept video](https://youtu.be/wOhGI9ZFLmU) on YouTube (sorry german for know). For disguising the whole topic there is now the [Group Filament Carousel](https://www.thingiverse.com/groups/filamentcarousel) on thingiverse. Every one who is interested in invited to join! Bill of materials 3 bearings 608 (most common ones) 3 countersink screws M5x20 3 nuts M5 2 countersink screws M5x25 (M5x20 are also ok) 2-4 binder clips Printing and Assembly The base is to be printed upside down. The model contains all required support. The clamp is to be printed on one of its sides, to obtain ideal layer orientation. The assembly is shown in this [video](https://youtu.be/19s8maf39_8). (The explanations are in German, but you will get the clue even if you don’t understand a single word.) After removing the little support brackets from the shafts inside the base the bearings are pushed onto the shafts and mounted with M5x20 countersink screws and nuts. The hub is just pushed in from the top. It snaps in and is held by the lower portions of the bearings, while it rides on theyer perimeters. The carrier is connected to the hub with four pins from 1.75mm filament. To make sure the holes are fitting the pins re drill them with an 2mm drill. The provided clamps are to fits 9mm and 6mm frames. Some binder clips might help to secure the bag if it gets lighter. Preparation of the coils is also shown in an [video](https://youtu.be/ENBaQnHx698). (Also German, but you will get the clue) The difference to the [“Filament Sample Dispenser”](https://www.thingiverse.com/thing:3542220) I published recently the carrier of this one fits the size of the refill coils in diameter and height.
