Hook for wire basket with safeguard / universal hook with countersink bores

Hook for a wire basket with safeguard - an installed wire basket will not fall off if pushed from below! Wire baskets vary a lot: Another (theoretically identical) basket from the same brand did not fit that nice. 

Fits 90 x 20 mm bars (with 0,5 mm play) so it can still be moved.

Printed in PLA (silk) and PETG - both works

Bonus: 

For universal use I also made a hook with countersink bores. I used two of them to mount a small existing shelf to the bar of the bed.

It may not fit exactly the dimensions you need but you may be able to stretch it in the slicer. At least this can give you some inspiration for an own design if necessary.
