About this model

Unfortunately my stock 30mm fan broke and i only have some 40mm fans lying around. So i created this mount for using a bigger fan. It does not collide with the heater block in any orientation, but as theres not much free space between the lower brackets and the top surface of the heater block it might get too hot. UPDATE: I removed the lower brackets, because it is impossible to snap it onto the heat sink without breaking it. At least when printed in PLA. You just push the heatsink from the bottom in this fan mount. If you print ABS you might try the first version. i dont know if it is flexible enough.
