Wand created for a birthday gift for a Harry Potter fan. It has space in the handle for 2x AAA batteries and a 3v 5mm LED fits nicely in the tip to allow many hours of Lumos spells!


Sketchup file contains work-in-progress models, as well as the simplification I had to do since my printer couldn't capture all the fine details accurately.

Model has been split to fit my tiny printbed - there's nothing larger than about 90mm. It can be glued together, but tolerance is pretty tight for batteries + wires + switch, so feel free to enlarge the model a little to make it an easier fit.

Circuit: 2x AAA batteries provide 3v which is fine to drive a 5mm LED with a simple switch at the top of the handle to make it go on and off.

The model was glued together with Bostik 5 minute epoxy which held well on the PLA. It was then coated with a couple of light coats of plastic primer, and then rubbed with Daler-Rowney Goldfinger (antique gold). Finally it was painted with acrylic black paint and rubbed-back when the acrylic was still wet to give an antiqued-gold appearence.

Random note for Potter Fans: To symbolise the bond between the friends in the books, JK Rowling based the wood for Harry, Ron & Hermione's wands off their birthdates in the Celtic calendar (which has a wood associated with each month of birth). The recipient for this wand was born in November, so the decorations are based on the Celtic wood for November which happens to be "Reed" AKA Scottish Broom.

is the led light separate, what type will i need, do i need a spring for the batteries, and do i put the batteries in at the bottom of the wand? pls reply

This is absolutely stunning, and I feel like I need to have this in my life. However, I hate sketchup with the murder-y passion of a thousand dying suns...

I tried to like it, I really did. I know it's highly recommended, and for someone with a particular skill-set other than my own, it probably makes unicorns farting rainbows leap forth from the screen. Three months of fiddling and wanting to throw my desktop out the window, and I uninstalled and found another software that was more intuitive for me.

Is there any way for you to post an STL so those of us who - not out of laziness, but out of ineptitude and frustration - can print this? Otherwise, I may have to ask internet strangers to do it for me, since installing sketchup for any reason on my machine would make me feel... unclean.

Oh by the way, can you convert it not on that Guitar website.

hey Tux is there any way you can turn the files into STL. files. My printer does not take the type of file you are letting people download. Thank you so much!

Please could you do a .stl file because i couldn't use cad if my life depended on it. Please, Please.

Your wand is great,  I also have a friend who is a Harry Potter nut.  I would like to build, but have no idea how to create the stl files from sketchup.  Any advise on how/where to learn?

There's a free plugin for sketchup that works well to convert to STL. Info is found here: http://www.guitar-list.com/download-software/convert-sketchup-skp-files-dxf-or-stlhttp://www.guitar-list.com/dow...

Any chance you are willing to post the STL for us lazy folk? This project looks great, I would really like to give it a go.

Wow! That paint work is crazy! If there is something that I lack in my "toolbox" these days, it's paint skills and I fear that that will be way harder than learning an CAD application.

paint it the solid color and then water down the black and wash it over the rough parts and wipe it off to see what sticks.. there are some neat paint tricks to be learned from a game called Warhammer.. good luck! and great thingi i hope to make someday for my fiance!

 Seconded.  That is a magnificent paint job for anything, let alone a printed part.
