IKEA Malm bed risers

Ikea's Malm bed has a steel bar in the middle that is lower than the wooden side edge and blocks their own Skubb under bed storage. But I will not be stopped from pushing my Skubbs all the way through to the other side, so I designed these risers.

They are ridiculously overengineered and come with the following features, all of which are totally free:

• 5 cm rise (about 2 cm are required for Skubb, but only if you pack them perfectly flat)
• Cutout for the stock feet. This should help with alignment.
• Springy grippers that grab onto the bed for easier installation

Malm has six feet and I suspect that all of them are load-bearing, so I would recommend printing six risers as well. PLA is probably not a good choice due to creep under load. For lack of a better (white!) alternative, I used PETG with 8 perimeters, 12 top/bottom layers and 10% infill. I'll probably notice if they fail.

I have the high, 140 cm wide Malm bed. Someone else has had a similar idea, but he must have a different Malm model than me. He says that his has 5 cm boards and a Roborock S8 can't pass under, whereas mine only has 4 cm thick boards and my S7 does pass.
