If you feel like Doing-It-Yourself and if you think this can be useful for your L 46 take the suggestion:
Use a trimmer for cutting a ceramic amphora and silicone glue for sticking the parts.
Use a bigger amount of silicone at the bottom of the cave to avoid the funnel format, against the risk of the eggs or fries being tightened.
Approximate dimensions of the cave:
2cm height at the entrance x 4cm width x 10cm interior length.
They will be grateful.
Have a good time!
