Parametric Tardis with LED hole by nopoe Aug 13, 2012

Description


If you just want a Tardis, check out the thing I derived this from. If you want a Tardis with a hole in the top for an LED and plenty of room for batteries and electronics, this is it!


This is like 98% Gossamer's work, but I needed to modify it a little to get a 5mm LED to fit nicely in the top. I also changed the hollowed-out section in the middle to a square instead of a circle. This leaves plenty of room for a battery to power the LED. Instead of a dome at the top of the hollowed section, I used a 4 sided pyramid subroutine taken from randyy's OpenSCAD Parts Library. http://www.thingiverse.com/thing:6021

The only new feature that isn't parametric in this design is the diameter of the recessed hole meant to catch the LED's flange if it has one. This is permanently set to one, but feel free to change it or remove that line of code altogether if you don't want it.

UPDATE (8/23/12):

I finally got the overhang right. It's parametric now, too. Go ahead and check out the instructions if you're interested.

Made two of these - one 40mm across the base and the other 25mm. I was impressed how good the detail is at this scale. Great thanks.
Yeah. I added a lot more room, a hole in the top and a feature to catch the flange most LEDs have at the bottom. The hollow area is enough to put a nine volt and current limiting resistor. You could make a discrete multivibrator and put it in there, but I recommend getting a Blinking LED with multivibrator built in. I ordered part number RL5-BB3020 from superbrightleds.com
I thought at first that this didn't add anything that /thing:10285 wasn't already doing. Then I checked /thing:10285 closer and... okay, this is different. Maybe you've got enough room to do some circuitry so the LED can flash.

Instructions

I updated the scad file to have a parametric overhang slope for the hollow section. I currently have it set to tan(30) which works fine for me, but you may want to modify it if your printer is really good or really bad at overhangs.

You may also want to change the height. The stl is about 97mm high, which can be problematic for a prusa depending on your setup. Don't scale the print with your slicing program, because it will also resize your LED hole, which is the defining feature of this print! :)
