This model is for creating a new replacement part for a Remington Model S-6300 Hair Straightener hinge cap.  The piece fits both sides and simply clips in as per the original.  

The two prongs that clip in a pretty small - I had some printer artefacts that needed a quick tidy up before use (0.3mm nozzle).  

The original hinge cap has a concave top (purely aesthetics) - this model does not have this concave side, it has a nice flat side to make printing much simpler.  I printed this in about 10mins :-)
