At a summer Make Camp we wanted an inexpensive way for the campers to jig up bracelets and other paracord weavings. A clamp for each end was devised that straddled a yard stick for easy sizing. With a trapped screw and nut the ends are easily adjustable to the right point on the yardstick.
The design was developed in SolidWorks and the parts were printed on the Makerbot Replicator in ABS.
Security is always an issue but occasionally you want to have your place of business more inviting. A simple clamp pinches the crash bar closed thereby temporarily unlocking the door. Having done this numerous times the trick to having it work the first time is to make sure the unit is not too thick and the fingers will fit between the backside of the crash bar and the window of the door. The nice bright yellow alerts someone that the clamp is on. In this case we personalized it for the venue so it doesn’t walk off.
The part was developed in SolidWorks and printed in ABS on the Makerbot in 3 hours, 5 minutes.
