LifeLike Teakettle Engine Replacement Coupler Assy

This is a simple to print and install coupler assembly for the LifeLike Teakettle engine series. The couplers on these older engines tend to break, which is what happened on the two I have. Here is one of them with a partially broken coupler:This assembly will allow you to replace that coupler and place your engine back into service.The old coupler is held in place by a keyed pin. To remove the broken coupler, you push down on this which will release it, allowing you to pull out the old remains of the coupler.However, once you do this, what usually happens is the plastic arm of the pin either breaks off completely or partially. So, any new coupler you try to install will have nothing to hold it.The new assembly deals with that easily. If you still have part of the old pin in place just bend it out of the way and remove it completely.Print both pieces of the assembly. The only part that requires any support is the coupler. I recommend printing each individually.<img src="https://makerwo
