An organic shelf that “grows” from your wall.
If you need a small shelf for anything you want to make visible every day (like your favorite Benchy or a small plant) this is the one for you.
This one is based on four 3d scans that I had for dinner afterwards.

Versions
Pleurotus_Eryngii_shelf_A and _B: The shelves in the default size
Pleurotus_Eryngii _shelf_no_holder_A and _B: The shelves without the cut-out intended for scaling down – must be mounted with glue or tape.
Pleurotus_Eryngii _shelf_small_A and _B: The shelves in the mini version (60% scale)
Pleurotus_Eryngii_holder_default: the holder for the default size with a screw-hole diameter of 5.5mm
Pleurotus_Eryngii _holder_small: A holder for the mini version – simply scaling down the default version would make the holder unusable
Pleurotus_Eryngii _holder_for_upscaling: If you want a huge version, scale up shelf and use this holder – the only difference is the screw-hole size of 3mm that will be usable when scaled.

Instructions
Print the shelf and holder
You can either screw or glue it onto your wall. There are various glue or tape products for wall fixation out there. I used 3M Tape. Old fashioned screws and dowels are the most reliable fixation.
Insert the shelf by moving it horizontally onto the holder until the holder is completely inside the cutout. Then proceed to move the shelf down and the holder locks.
Enjoy!
