30mm Driver to 40mm Fan Mount
thingiverse
On my Eleksmaker A3 Pro, the laser has been upgraded to a larger 2.5W laser diode. Instead of using the TTL Driver, I reused the driver from the orginal laser as it can handle the larger diode. The issue is that the original laser used a bolt pattern that matches a 30mm fan, and the new laser uses a bolt pattern of a 40mm fan. This is the adapter to attach the laser driver to the larger laser diode and still allow plenty of clearance for airflow.
