Ender 3 Horizontal Spool Holder

Description

Due to a lack of vertical space I decided to mount my Ender 3's filament spool horizontally. The design uses 5x 608 bearings to keep the rotation of the spool very fluid to make the Ender 3's life easier to feed the filament. The design is slightly overkill but I had the hardware to spare. I would recommend using my Ender 3 Filament roller guide top with the -angled- upper filament guide to ensure smooth feeding of the filament. www.thingiverse.com/thing:4279234 Minimum hardware needed: 5x 608 bearings. 3x M5x20 nuts and bolts For T-Slot mounting method: 2x M5 T-Nuts - These come with the Ender 3! 2x M5x15 bolts For saddle mounting method (Optional): 4x M6x45 nuts and bolts, I would reccomend using 8x washers as well. For a supported center (Optional): 1x M6x45 nut and bolt - the bolt head must fit into the top rail T-Slot 1x washer. There are several versions and ways you can make this. See the table in the photos to see which ones to use for which style you want: 1) For the center bearing support I used a M6x45 bolt that fit inside the Ender 3's top rail V groove, but if you don't have one there is a printed alternative which presses through all of the bearing centers. 2) My preferred version used a side skirt between the bearings, it has no function other than to make the holder look a bit more pleasing. They have a built in raft as part of their design to prevent warping, and they are separate from the main center as to make it easier to print (using less supports) They press fit into the center, you can use glue but it's not really needed. 3) A center spool guide holds the spool in the center of the holder. These come in sizes from 50mm to 65mm diameter, just match them with the ID of the filament spool you're using. I made a whole bunch of them just download the sizes you need: https://www.thingiverse.com/thing:4348684 4) Mounting to the Ender can be done using the supplied M5 T-nuts used to mount the stock Ender 3's spool holder bracket, but youll need some slightly longer M5 Bolts. I also made an additional pair of mounting brackets to make sure there was no chance of the spool holder coming off. You can use either method or both. Print the main center component (either style) upside down (with the 3 spokes flat on the bed) to save filament wasted on supports My files have a .2mm gap between parts, if your parts aren't fitting try changing you slicer settings to fit. Please note in the photos the base bottom is an Acrylic disk and not 3D printed. I already had this part and wanted to use it. However the Base Bottom .STL is the exact same size and uses the same hole layouts. if you don't want it as thick, just scale it in the slicer.
