BIBO 2 TOUCH over center hinge with magnet hole and catch

thingiverse

This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/bHZwU9TTyEm I designed this hinge to solve the problem of the BIBO's door constantly flapping down while working on things. It is nearly identical in looks to the original hinge, but this one does away with the need for the nylon grommets that come with the original hinge/door. It moves slightly more than 180° so it doesn't flap back down. Originally I had designed it with 8mm diameter x 3mm thick "rare earth magnets" which failed to sufficiently hold the weight of the door open. The holes are still present under the extended area of the hinge but they no longer serve any purpose as the adjusted angle of the hinge solves the problem. Also added are clips or catches on each side of the hinge that rub slightly while the door is open. They give it just a bit of friction to help secure the door over center. The barrel of the hinge is approximately 3.5mm across and will fit a bolt with a size of around 3.4mm or 1/8" diameter and 1.8" / 45mm in length. The very last barrel on the top hinge is slightly smaller than the remaining ones so that the bolt will thread into it. If the thread on your bolt is too large to gently screw in, then drill it out slightly to prevent it from cracking the plastic. I used a threaded rod, cut to length with a dremel cutoff tool and then slotted at the end with the same cutoff wheel and screwed it in with a jewelers screwdriver for completely flush hinge ends.
