ReDuplicator Rails + STL fixes

thingiverse

ReDuplicator converted to MGN12 rails on X and Z. New 90deg fan duct should allow 255mm max z height (I got 236mm with the 45deg) Most of the original STLs reused had small defects or didn't line up so I fixed those while I was at it. Fixed original files: Feet Part fan duct 45deg Part fan mount Y Idler Y motor mount Y rod holders (all) Y belt holder The belt holder in this and the original requires longer screws to work; at least 12mm if using the stock bed, with my 3mm aluminum bed I would need 14mm. I don't remember from building but I think most of the other screw lengths in the directions are wrong, so it's best to just get an assortment. Ideally you should get new y rods at 400mm and TR8x2 leadscrews, but they aren't necessary The screws that come with the titan aren't long enough to actually allow any mount, so you'll need 35mm screws and either print a 2-3mm spacer or stack washers under the screw head.
