Garage drain cover

As I was tiling the concrete garage floor, i needed a solution for the already existing drain cover. Since the drain was old (rusty), round and lower than the new tile floor, I made a square frame which was glued with the tiles. In this frame a square drain cover can be placed. The structure of the drain cover comes from the 15% grid infill pattern, which is made visible by removing the top and bottom layers. Made it from PLA but likely will replace it with something more durable when needed.
