Key Clip

Here's my trolley key clip design. I attached it to a key ring using a simple clip. Print settings: Printer: xyz davinci 1.0a Rafts: No Resolution: 0.1 Infill: 90% Post-printing, I might need to separate the gate from the main body. My printer bridged the small gap slightly. How I designed this trolley key clip is as follows. I started with two circles, 15 and 10mm in diameter. A sketch joined them together and was then extruded to a thickness of 3mm. After that, all parts were joined together. I made a copy of the original design, scaled it down to 0.9, centered it over the original, and then subtracted it from the original. I also created a 12mm circle and a 6mm diameter octagon, extruded them, and then subtracted the octagon from the circle. The result was joined to the hollowed-out form to create the key ring hole. Next, I split the form in half and removed one side. Then, I used the cube primitive to create the gate and played around with its angles since I couldn't change the object's center point in 123D. After joining it all together, I was ready to print. That's basically how I designed this trolley key clip, aided by a generous amount of port, which probably didn't help!
