Gikey, the gyro keyring

thingiverse

Gikey prints exceptionally well, actually it is designed to be printed without any support materials and turns out great in PLA at 0.2mm and 0.3mm resolutions. The new version of Gikey created in OpenSCAD can be edited with the Customizer tool. The uploaded file includes custom settings: Gykeysize = 15; // [12: Small, 15: Medium, 17: Large] LenghtGikey = 14; // [12: Small, 15: Medium, 17: Large] // size of the nozzle of the printer nozzlesize = 0.5; // [0.1: Really Small, 0.2: Medium, 0.3: Ok, 0.4: Large, 0.5: Extra Large] // The wall size is this times the nozzlesize wallsizemul1and2 = 3; // [1: Thin, 2: Ok, 3: Large] // The wall size of most internal is this times the nozzlesize wallsizemult3 = 2; // [1: Thin, 2: Ok, 3: Large] // Space between layers multiplier Layers_Space = 2.8; // [1: Thin, 2: Ok, 3: Large] Old Version: If you want to modify the file, simply go to https://tinkercad.com/things/22DUMc27624. Thanks to http://www.thingiverse.com/thing:644217 for your excellent idea. Gikey stands out because inner rings are scaled versions of outer ones in three axes. I found it easier to print especially with DIY 3D printers like mine, also achieving smooth rotation - check https://youtu.be/kKWDhZBpK_Y for example.
