Allen key/hex key extender

This is an extender for Allen/hex keys and also cloud be used as handle for hex bits. There is a .stl-file included with dimensions that fit the key I have to use for bed-leveling for my 3D-printer.

The following sizes can be adjusted:

  • inner diameter of the key (consider adding room for shrinkage)
  • height of the extender
  • depth of the hole for the bit
  • thickness of the shell (use a multiple of your nozzle)
  • diameter of the base

This should not only work for Allen/hex keys. Everything with a hex-shape e.g. hex bits should fit if adjusted to the right size. If you are looking for a hex (or even round) pencil extender you might want to have a look at the dice pencil extender or cap.
