The shoe storage cabinets Ikea Trones require fixing because otherwise opening it becomes unbalanced and tilts forward, to mount close to the passage of water pipes in the bathroom and at the same time not wanting to pierce with drill tiles, I designed with FreeCAD this plate.

For gluing I proceeded in this order:

1. Positioned the two shoe storage cabinets stacked
2. Marked the matching of the mounting holes high on the tiles using a permanent marker
3. Removed the shoe storage cabinets
4. Cut a piece of paper of the size of the plate, 50×50 mm, I have made a hole in the center of the paper template I did match with the mark on the tile
5. Scored the edges of the paper template on the tile, by this way I got a reference for the perimeter of the plate to be bonded.

I used silicone to glue the plates to the tiles, the silicone can be easily removed with a scrap blade without leaving their mark on the tiles when they want (that is, if my wife ordered me :) ) remove the shoe racks from that position.

I printed the object exactly as it appears in the STL file, with the base to stick the tiles on the printing plate and I did not use support material in the slicer to support the “mushroom”.
