About this print
A customisable, clip-on fan bracket designed to attach cooling fans of various sizes to PCB boards, including RAMPS boards and Raspberry Pi units. The bracket can be printed as a compact two-hole version or a full four-hole enclosing form, balancing material use against airflow and rigidity. PETG is a practical choice for this type of electronics accessory, as it tolerates the modest heat produced by nearby components better than PLA.

An easy way to generate brackets to attach any fan to any PCB board. A list of pre-defined brackets included.
The script was initially meant to generate fan brackets for the RAMPS board but I decided to make it fully customizable: it now allows you to create brackets that take fans of any size, snap onto PCB of any size, can have any height, but probably best of all features is that you can generate both mini-brackets (2 holes) as well as full brackets (4 holes, fully enclosed on two sides), to balance between saving plastic vs. rigidity and improved air flow.
While this was meant for PCBs, feel free to experiment it could probably be used for many other scenarios, for example to attach a fan to a NEMA17 motor or to space two PCBs by attaching brackets back to back, etc.
__UPDATE__ :
It can now generate PCB supports with no holes (example scenario: Raspberry Pi or Intel Galileo feet). Specific changes:
- fan cutout (and the screw holes) can be removed entirely now 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 bigger than the PCB (for example when using an 80mm fan on RAMPS) the bracket will be generated with "wings" and the fan will attach on the outside of the bracket to those wings, otherwise the fan will attach on the inside.
Additional benefit compared specifically to thing 138370: the brackets should now slide along the board without hitting the reset button and should also slide better along Arduino or RAMPs PCBs which have solder joints or connectors really close to the edge.
Formatting may have been simplified. These are the independent maker's instructions and fitment claims; Hark Tech has not independently verified them.
Printing MOAB - MOther of All fan Brackets
For MOAB - MOther of All fan Brackets we would normally reach for PETG — it is tougher and more heat-resistant than PLA, ideal for parts that take load or live somewhere warm. We set the layer height, wall count, infill and supports to suit the model and how you will use it, and those choices are already priced into your instant quote. Want a specific colour or material? Tell us and we will match it where we can.
