thingiverse

I designed this to fit 5 Rolls of Filament into my Besta / Stuva Enclosure for the Prusa MMU 2.0.\r\n\r\nThere is also a smaller Version with a total width of 500mm: https://www.thingiverse.com/thing:3328425\r\n\r\nAnd a wider Version with 560mm: https://www.thingiverse.com/thing:3328421/files\r\n\r\nNow with a short and long frame as a version to daisy chain the spool holder for more spools.\r\n\r\nIt uses the Parametric Auto-Rewind Spool Holder (https://www.thingiverse.com/thing:3252111) with a modified Axle to mount the Spools.\r\n\r\nIt has 6 sunk holes to mount to the backside of the Cabinet.\r\nThe Brackets are mounted using M4 countersunk screws with a length from 12 to 20 mm.\r\nThe Endcaps are mounted with M3 countersunk screws.\r\n\r\nYou need:\r\n\r\n6x Bracket\r\n2x Frame Long or 2x Frame Long stiff (the first is faster to print, the second is more rigid)\r\n1x Frame short\r\n5x Axle\r\n10x Endcap\r\n\r\nHardware:\r\n\r\n12x Screw M4 countersunk, length from 10 to 20mm.\r\n10x Screw M3 countersunk, length from 10 to 15mm\r\n\r\nPlus 6 Screw to mount the assembly, I used 3.5 x 16 countersunk wood screws.\r\n\r\nAll parts can be printed without support Material.\r\nSpool & Protector must not exceed a length of 95 mm.\r\nI used these Settings for the spool:\r\n\r\noutput = hub\r\nreferenceSpoolInnerDiameter = 50\r\nreferenceSpoolWidth = 80\r\nsecondSpoolInnerDiameter = 0\r\nsecondSpoolWidth = 55\r\nhubSpringEnable = no\r\nhubFlushWithReferenceSpool = no\r\naxleDiameter = 8\r\naxleSetLength = 0\r\naxleRotationStopLength = 12\r\naxleRotationStopWidth = 0\r\naxleRotationStopHeight = 11\r\nsetSpringDiameter = 120\r\nspringBladeWidth = 6\r\nbearingDiameter = 22.2\r\nbearingWidth = 7\r\nspacerHeight = 3\r\naxleGrooveForSpacer = no\r\n$fn = 80\r\nspringBladeThickness = 1.1\r\naxleClearance = 0.15\r\nprintedAxleClearance = 0.1\r\nspacerClearance = -0.1\r\nspringBladePitch = 3\r\nspringRimThickness = 2\r\nspringAxleThickness = 1.5\r\nspringExtraRim = 1\r\nspringClipExtraClearanceIfSpringAsShaft = 0.3\r\nspringClipPointExtension = 0.3\r\nhubBackPlateThickness = 2\r\nhubClipCount = 8\r\nadapterRimThickness = 2\r\nhubSlitRelativeLength = 0.8\r\nhubClearance = 0.5\r\nspringProtectorStyle = 1\r\nspringProtectorThickness = 2\r\nspringProtectorSpokeCount = 5\r\nspringProtectorSpokeWidth = 2\r\nspacerWall = 1.5
