"Medium" Puzzle

Got this puzzle at a craft fair one time and the guy had it arbitrarily labeled as "Medium"; no idea what the actual name is other than that. Recently rediscovered it on here, but the model was a bit small; so I made it larger (75mm instead of 50mm) and added some chamfers to the corners to make it better for printing (parts take up 115mm x 155mm altogether).

Printed with PLA at 0.2 layer height and Cubic infill set to 10% (after splitting all the parts into separate objects for better infill calculation).

As always, any input or suggestions are welcome.

Resized to 75mm (originally 50mm), and added chamfers, as well as arranged all the parts for one puzzle on the plate
