Shelf support pin for cupboards and wardrobes

Problem: 

The support pins for the shelfs in an Ikea Pax wardrobe broke and the hole got damaged. 

Solution:

To repair this I designed a shelf pin that extends down and fits also in the next 2 holes so that the weight of the shelf is distributed and the broken hole does not matter.

The source file for openSCAD is attached, so you can print your own support pins, depending on the size of the holes, the distance between the holes and so on.  Some example STLs are there with 1 to 3 pins. 

Printing instructions:

Print with supports and 50% infill. Layer height 0.2 mm.
