Model Railroad, Covered Bridge
Description
This Is A Model Of A Covered Bridge For Model Railroads. This Design Is Based On Pictures On The Internet And Does Not Model A Specific Bridge. This Bridge Is Roughly Scaled For O27-Scale Trains (E.G. Lionel). The Design Was As Big As I Could Make It For A Makerbot Replicator2 With A Build Volume Of 11.2"L X 6.0"W X 6.1"H (284-Mm L X 152.4-Mm W X 154.9-Mm H) As Built, The Bridge Can Handle An O27 Scale Train But It Is A Very Tight Fit. You'Ll Have To Have At Least One Straight Track Outside Of The Bridge. At Full Scale, The Bridge Opening Is 65-Mm Wide By 102-Mm High. When Printing The Bridge For Other Scales... - For O27, Scale By 105% To 110% If Your Printer Has A Bigger Build Volume (An O-Scale Probably Won'T Fit At 100%) - For S, 100% Is A Good Size - For Ho, Scale By 65% To 70% - For N, Scale By 40% To 50% - For Z, Scale By 40% To 45% A Full-Size Bridge Took Me Over 20 Hours To Print.
