MOAB - MOther of All fan Brackets

cults3d

A simple method is available for creating fan attachments that can be fitted onto any Printed Circuit Board (PCB) board. A selection of pre-defined brackets are included. Initially, this script was designed to generate fan brackets specifically for the RAMPS board but I decided to make it fully customizable: it now allows you to create brackets that accommodate fans of any size, snap onto PCBs of any size, can have any height, and a notable feature is that you can generate both mini-brackets (2 holes) as well as full brackets (4 holes, enclosed on two sides), striking a balance between saving plastic and achieving rigidity while improving airflow. Although this script was intended for use with PCBs, feel free to experiment; it could likely be used in various other scenarios, such as attaching a fan to a NEMA17 motor or spacing two PCBs by attaching brackets back to back, etc. UPDATE: It is now possible to generate PCB supports without holes (example scenario: Raspberry Pi or Intel Galileo feet). Specific changes include: * The fan cutout and screw holes can be removed entirely to produce spacers or PCB feet. * Hex nuts resize with screw size (need to validate in practice). * Cross-brace is configurable and can also be removed. Note: If the fan is larger than the PCB (for example, when using an 80mm fan on RAMPS), the bracket will be generated with "wings" and the fan will attach to those wings from the outside of the bracket; otherwise, the fan will attach inside. An additional benefit compared specifically to thing 138370: The brackets should now slide along the board without hitting the reset button and also slide better along Arduino or RAMPs PCBs which have solder joints or connectors close to the edge.
