IOM Folding Yacht Stand, 4 Positions

thingiverse

Inspired by the DF65 yacht stand, I decided to create my own version based on sakunamary's design from Thingiverse, which can be found at https://www.thingiverse.com/thing:2139038. For the International One Metre (IOM) class, I also drew inspiration from David Jenson's design, available online at http://nmsclub.org/files/documents/IOM-Boat-Stand.pdf and http://nmsclub.org/files/documents/IOM-Boat-Stand-CradlePDF.pdf. The included files cover both fixed arms and folding arms, with the option to install three 12mm magnets in the folding arm to keep it secure when folded. The aluminium tube used is a 19x19x1.2mm, 3m length tube available at Bunnings, as seen on https://www.bunnings.com.au/metal-mate-19-x-19-x-1-2mm-3m-aluminium-square-box-tube_p1079470. For the hinge, I used a Continuous 915mm Stainless Steel hinge cut to length, which can be found at Bunnings on https://www.bunnings.com.au/hinges-continuous-915mm-stainless-steel-continuous-hinges_p4161173. The screws required are M5 x 50mm (2 off) and M5 x 40mm (4 off). The handle is a 20mm Dia piece, which can be any material, but I used electrical conduit for mine. I included the bulb support, which is not necessary but helps hold the boat better in its lowest position. This support fits bulbs up to 40mm dia and was printed with flexible filament and 10% infill, just like the feet and collars. All other parts were printed in PETG without any supports, except for the tube joiners, which have internal support pieces that should break out easily. The 5mm bushes are purely decorative and not required for function. To assemble the arms, I used epoxy to glue the magnets into place, then covered them with supplied caps. Additionally, I added velcro next to the hinges to help hold the arms in position. After assembling the arms, use 4g X 25 screws to mount the catches (see photos). The tube joiners were fixed to the tube using small Stainless Steel self-tappers. For an alternative option, you can use cord and clips to hold the legs apart instead of the leg brace, as shown on the original plans.
