Wanhao duplicator I3 plus fan guards

These are fan guards for the wanhao duplicator I3 plus, or clones. They might fit as well on other 40mm fans.

For the wanhao I3 plus you will need to print both files, one of them is for the 'extruder fan' and one for the 'cooling fan'. Two files are needed since the stock configuration of the screws is different on these fans.
