Parametric motorcycle/bicycle handlebar watch mount

thingiverse

This is a mount designed to replace the band from any standard watch, to mount to any handlebar or other round tube. The included STL file is designed to mount a Casio F-91W to a standard 7/8" (22.25mm) motorcycle handlebar with a #6-32 x 1 in. machine screw and nut. (use a locking nut for best results) It is designed to minimize print time, and work without hinges. I have tested with PETG and PLA and it retains enough flexibility to go over the handlebar without breaking. The Fusion 360 file that is included should allow you to modify the mount to fit many different watches, handlebars, and bolts (within reason). The following are the parameters that you may want to change: * **bardiameter** - default 22.25mm - the diameter of the hole for the handlebar * **pindiameter** - default 1mm - the diameter of the pin that goes through the watch band * **strapdiameter** - default 3.5mm - the total thickness of the strap where it goes around the pin and attaches to the watch * **strapwidth** - default 18mm - the size of the watch band * **pincenterdistance** - default 35mm - the distance between both pins on the watch, measured to the center of the pin opening * **casebacktopincenter** - default 2.25mm - the distance between the centerline of the pin and the back of the case, in other words, the distance that the pins need to come up from the back of the case. Err on the side of too much, rather than too little. * **screwhole** - default 4mm - the diameter of the hole for the fastener. Round up with your measurements so that it doesn't fit too tight. * **headrecessdiameter** - default 7mm - the diameter of the countersink. Again, round this up a little bit because a snug fit is not desirable. * **nutdiameter** - default 8mm - the size of the nut measured from flat-to-flat. You may or may not want to round this up depending on if you'd like the nut to be retained and your particular printer. * **nutrecessdepth** - default 3mm - a recessed pocket for the nut so that you don't need to use a wrench on the back side.
