A Minecraft (tm) torch with wall mount and decals, for flashlights or other, custom light sources.

You expect your children to help in the household?
Print this - problem solved.
Promised ;-)

Do NOT print the included STL files.
These are only examples to clarify the "printing number" in the OpenSCAD source file.
This file also contains a lot of explanations and (hopefully) other helpful notes.

You'll need a flashlight with a rear button. Preferably, the top lens
can be detached.
By default, the torch has the dimensions (40 x 40 x 200)mm.
Any flashlight up to a length of ~140mm and a diameter < ~34mm can be used.
If it does not fit, the torch's size needs to be increased.
Keep in mind that this also requires scaling the the print-sheet, with
the Minecraft torch decals on it.

The flashlight edition of the Minecraft Torch consists of:

• bottom part (handle; the torch itself)
• top part (the "flame")
• fixture ring, to hold the flashlight in place
• pusher, fits inside fixture ring and pushes the flashlight power botton
  For the "power cord edition", please see the notes in the OpenSCAD source file.

• unpack "Screw_Library.zip" to the same path as the OpenSCAD file
• open the OpenSCAD file in an editor (or the OpenSCAD IDE)
• scroll down and find the line
  PRINTPART = 22; // choose which part to print
  This is where you specify which of the parts should be printed.
  Each of them is listed in a table, right above this line and most
  of the parts are included in the download section.
• the table above the print part selection line clearly shows what the selected part can be used for:
  PRINT -> printing export of final parts
  TEST-PRINT -> printing export of reduced test prints
  EDIT -> for tuning/viewing/editing inside OpenSCAD
  SHOW -> shows an overview of what you designed
  The three test parts 10, 11 and 12 are shown in the image:
  top left: where the flashlight's head should fit in
  top right: thread of the "bottom part" (the torch itself)
  bottom: the thread of the fixture ring
  Print these to make sure that the head of the flashlights and the threads fit. The small prints save a lot of time and material.
• begin to modify it ;-)
  Yes, it definitely will take some time, but I am sure you'll get the clue.
  The OpenSCAD source file also contains an ASCII drawing which might help identifying the parameters and what geometry they change.

NOTES FOR PRINTING:

• BOTTOM PART:
  Print top-down, like already prepared in the STL output (print mode).
• TOP PART:
  Needs to be printed in "vase mode", with no infill and open top.
  Usually one perimeter line is all you need.
  Keep an eye on "tTopCut", which determines how much material is cut off the bottom part
  to make the top part slide on it.
• FIXTURE RING:
  It should not be required to add support structures.
  The overhanging thread will print nice if you slow down the machine a little (30..50mm/s)
  and keep the layer height <=0.2mm.
  I set infill to 33%.

The wall mount has a slot and a hole at the bottom so that a Minecraft torch can be put in or taken out while a cable is attached to it.

UPDATE 9/2014:
I included the missing screw library, which can also be found here:
