Fingerboard Half Pipe

thingiverse

The object consists of three sections: A left side half pipe with roll in ramp, a center half pipe, and a right side half pipe with roll in ramp. The first file contains one of each section of ramp. Additionally, each section is also available as a separate STL(usefull for smaller print beds, or to expand the half pipe in length). To print a complete halfpipe you will two copies of each section. Additionally, the center section can be printed on its own to extend the size of the quarter/half pipe. Each ramp piece features realistic coping, and a safety rail, so it looks and functions like the real thing! The default print orientation is for each piece to lay on its side(see first image) and all three sections are designed to be arranged on the print bed as show which will fit on a 200mm x 200mm build plate. If you have a smaller bed, or prefer to print one section at a time, you will find that the additional files contain just the named section of pipe(Left, Right, Center) but should also be printed laying down as pictured. This orientation allows printing without supports. Another advantage is that the layer lines will be vertical when the piece is used in its normal orientation, which will allow for a much smoother ride for the fingerboard. Though the object is solid and relatively big in volume, I left it solid as opposed to hollowing it out so that no supports will be needed inside the object either. It should print just fine with a very low infill percentage, as long as you make sure to solid fill a few extra top and bottom layers, which will also help with rigidity while in use. Additionally I would recommend using several shell layers which will help the top curve of the drop in ramps, and ensure that all the ramp faces remain rigid. Estimated time and material to print a single section: 7 hours at 70 grams* Estimated time and material to print complete 6 section halfpipe: 42 hours at 420 grams* Approx. size of each section is: 120mm x 130mm x 90mm *Time and material estimates based on a print speed of 100mm per second, infill at 10%, Top/Bottom/Shell thickness at 1.2mm, a .4 nozzle at .1mm layer height, and no adhesion or support options on.
