Folded lamp shade spotlight for GU 5.3 bulb

thingiverse

This is a remix of the Folded Lamp shade I which found here on Thingiverse and loved it, but wanted to tweak it a little bit for my own needs. I've split the model in two parts: - The actual shade - A cover with pre-drilled holes for the standard GU 5.3 connectors. This cover includes holes to allow hot air to escape Non-printable parts needed: - Two M2x10mm bolts to hold the adaptor in place - Two 2mm screws to hold the two pieces together - 1 GU 5.3 connector - 3mm wire I've used the following print settings with good results: - PLA @ 215/210 degrees, 65/60 degrees bed temperature - Layer height 2.5mm - Infill: 0% up until the screw mounts, 20% honeycomb above that (if your slicer doesn't allow you to select different settings for different regions, I have used 5% rectilinear for the whole print with good results. 20% honeycomb for the top cover - 1 Outline/perimeter shells - the part doesn't need any structural rigidity. Plus, using less material helps making the shade translucent. I have also found it tricky to align the prongs with the connector so I designed a little tool to help push the bulb in/out - also included in the files. I have used this design successfully with 7W GU5.3 12V bulbs. I suggest you don't try to use regular incandescent bulbs because the heat would most likely cause the part to melt or even worse, catch fire. UPDATE 21/02/2018 - Modified the top cover a bit to give some extra room for the wires - Changed recommended print settings
