If you want to use an Ikea Kura tent on a different bed, this might work for you.
I have a couple of Delta children low loft beds (https://www.deltachildren.com/products/low-twin-loft-bed-with-guardrail-and-ladder) and wanted to use an Ikea Kura tent on them. This makes it so you can snap the Kura tent onto these adapters, slide the adapter over the bed rail, and then use a cheap reusable velcro tie to secure the adapter to the bed.
I modified a bed adapter from "relet" on Thingiverse so that I could secure it with velcro cable ties instead of relying on the “clamp” on the original model. I also punched some holes to save a bit of material.
I printed this upside down (the way it comes in the model) and my mk3s had no problems with the bridging on PLA or PETG. 0.30mm layer height, 7% infill. Takes about 1h 30m to print each one, and you need 6 for each tent.
The author remixed this model.
Fixed at 18mm space for bed walls, removed “spring”, removed some material for efficiency, added velcro strap slots
