its been awhile, 4+ years, wow. We will have to get better at keeping up the blog.
This is a neat project and a great application of 3D printing in a commercial space.
There is a local company that supplies hard to find, generally out of production, replacement hardware mainly for windows in doors in the residential and commercial space.
The owner came to E3 with a problem. There were literally hundreds of high end sliding doors in a local condo building that had various small components that had worn out over time. Replacements were not available from the OEM (Original Equipment Manufacturer). Replacing each door set would cost thousands of dollars and was not financially feasible yet residents were upset about their non lockable sliding doors in this high rise.
There were two parts The first was the sliding lever which the user moves to engage or disengage the internal latch. The second was the internal latch. The lever was made from an injection molded plastic with a steel pin insert. The latch was diecast from inexpensive metal.
E3 took available samples and reverse engineered the original parts and designed drop in replacements which could be 3D printed from high strength nylon. The parts could be produced and sold to the customer for a low price and high value. ie., they were able to avoid the cost of entire door replacements.
