Hardkernel Odroid XU4 3D Model

thingiverse

This provides the ability to show or view a representative model of the Hardkernel/Odroid XU4 ARM processor board. The primary use case for the model is the development of 3d printed cases for the XU4 board. The model generated is *not* suitable for printing. This leverages v1.1d of the XU4 Model script originally provided by user hominoid on the Hardkernel/Odroid support forum at www.forum.odroid.com. Reference the 'XU4 Model for OpenSCAD' thread at URL https://forum.odroid.com/viewtopic.php?f=97&t=26243 for info on that origin. Odroid XU4 Model Version 2 is a major revision to that v1.1d script. Comments at the top of the openSCAD file describe the enhancements from the v1.1d origin. The scad file is heavily commented, and a user guide for the model has been included in PDF format. The model would normally be accessed by "including" this scad file within the higher level design, and then using the odroid_xu4 module to create the model. For higher level designs to access them, key physical characteristics of the XU4 are provided in a separate file. File Odroid_XU4_Parameters.txt should be downloaded and placed in the same directory as the scad file. Various parameters allow the model to be tailored for a desired configuration. Parameter emmc_type specifies whether an emmc module should be shown as an installed option. Parameter sd_type specifies whether a micro-SD card should be shown. For the micro-SD card, the card STL model by Ubergeekking from https://www.thingiverse.com/thing:710938 will also need to be downloaded and placed in the same directory as the scad file. Parameter hs_type specifies the type of heatsink to be shown on the XU4. Heatsink options include no heatsink, the original OEM low profile heatsink shown without a fan, the original OEM low profile heatsink shown with a fan, the OEM passive heatsink (as used on the Odroid XU4Q), a flat plate heatsink, and two variations of the gdstime "gold" heatsink. The gdstime heatsink can be shown in a "normal" orientation that assumes gdstime mounting hardware will be used, or in a "rotated" orientation that provides improved thermal performance but requires the use of custom printed adapters for mounting the heatsink. Parameter perch_t defines the height or thickness of any shim or perch installed between the XU4 and the heatsink by the user. No perch or shim will actually be shown on the model, but the model will reflect the heatsink being raised up by that amount. Parameter opacity allows the XU4 model to be generated anywhere between very transparent and very solid. Parameter a_type defines whether the custom heatsink adapters available for the gdstime heatsink are to be clear through-hole or nut-trap type. The STL file in the listing is provided only for viewing an example with Thingiview - it is not intended to be printable. Various screen snapshots show what various configurations of the model look like in openSCAD. An example of a case design leveraging use of this model is the Configurable Odroid XU4 Open-Frame Case at https://www.thingiverse.com/thing:2655875
