Pavement stone riser for Ikea Lack enclosure

My Ikea Lack enclosure has an airvent below the pavement stone, so I needed a riser to pull it of the base. 

This riser gives enough clearance for good air intake. There is little to no drag around the print bed, and with a decent filtered vent in the top the temperature is very stable.

Printed in PETG with 0.4mm nozzle and 0.2mm layer height. I used 40% infill for strength and stability.
