XU4 Model for OpenSCAD v2

Unread post by klunkerbus » Sun Nov 19, 2017 3:47 pm

I've created an updated version of hominoid's XU4 openSCAD model. It is available on Thingiverse at https://www.thingiverse.com/thing:2655812

Hominoid's original XU4 model is from the 'XU4 Model for OpenSCAD' thread at viewtopic.php?f=97&t=26243.

Changes from the v1.1d origin include -
- Isolation of XU4 physical parameters into standalone parameters file to enable use in other openSCAD files (like a case design)
- Simplified coloring (ex: eliminated black since black doesn't show shading in rotation views)
- Addition of the transparency/opacity ability to the overall model and all model elements
- Added ability to show heatsink raised by a shim or perch
- Improved realism of heatsink fin quantity and sizing
- Added means to show SD card inserted into micro-SD connector
- Heatsinks now placed at their xy center to facilitate z-axis rotation
- Each component type now has separate module to facilitate future reuse on other boards
- Component elements are translated to origin best suitable for placement and rotation of that element type.
- Improved geometry mesh to minimize "ghosting" in openSCAD model view & rotation
- Replaced at least some hardcoded numbers with defined parameters for understandabilty
- Removed from the file the case-level accessories not specific to the XU4 model
- General openSCAD scripting structure
- Added various message outputs to the openSCAD console pane
- Extensive commenting
- Provision of a user guide

An example of a higher-level use of this XU4 model is the Configurable openSCAD Open-Frame XU4 Case at viewtopic.php?f=97&t=29066

Very nice improvements!
I've just picked my favourite one from your gallery.

BTW, where did you buy the cooling fan?

Thanks for the feedback. That image is shown with the 7mm fan I happened to order with the XU4 from Ameridroid. https://ameridroid.com/products/fan-40x7mm-5vdc-quiet

I've added a finger guard to the fan. I believe it is a Qualtek QSG-40-02 that I had previously ordered from Digikey as part of one of several 3d printer upgrades I've went through.
