Hedrons are ancient stone monoliths found throughout the plane of Zendikar. When properly aligned, hedrons become powerfull tools of binding. 1
This is my Hedron project. I've always wanted something iconic from Magic the Gathering to sit on my shelf of geeky staples ( you know the usual, Sonic screwdriver, T-Rex figure, Lady Deadpool figurine , etc etc. ) and with the release of the Battle for Zendikar block , I realized that the perfect object had been staring me in the face since October 2009.
I've seen some Hedron models before, but none of them were quite right to me, they got the patterns wrong , or just looked off in some way , so I set out to design my own , and this is the final result. Well these are the final result , because there are two variants here.
I started out by making a smaller Hedron that easily fits in the palm of your hand Such as this. But once I'd finished it , I realized that A) it was a tad small for display on my Geek shelf, and B) the spacing on the interior was just BARLEY enough to fit a 2032 Battery with two LEDs taped to it. So I scaled it up, and designed the larger version to have built in spots for 6 LEDs ( 4 in the center pieces and 2 on the battery holder holder ) , a AAA battery holder ( AA would probably fit as well I just had a AAA ) , and a switch so it could be turned on and off easily.
I couldn't be more happy with the final result.
The files contain both versions , the smaller Hedron ( STL files starting with Hedron ), and the Bigger Hedron ( STL files starting with BH ). The bigger hedron design includes STLs for a base for displaying the hedron , as well as a interior mounting piece for the switch , battery holder and two of the LEDs.
I hope you like my Hedron project! I'm happy to help with any questions as always!
--------- Update March 6 2016 ----------
Added a new Small side file ( BH_SideSmallRC_ButtonHole.stl ) that has a hole for a Self-locking switch 8 x 8mm ( http://www.dipmicro.com/store/SWITCH8X8B )
Added a new file ( BH_ButtonHolder.stl ) that will hold the switch in place if glued to the inside of the previously mentioned side piece.
- Added a new files ( BH_BaseLarge_Magnets.stl ) & ( BH_BaseSmall_Magnets.stl ) with spots for 1/4" diameter rare earth magnets to be used to hold the pieces togeather instead of using the keyhole slots.
Supports were needed only for the long tapering section of the larger triangular side pieces and were extremely minimal.
I did a filament swap part way through on the side pieces. I started with clear PLA, then just before the final flat layer of filament , I switched it to gray PLA, so that most of the interior face of the side pieces facing the LEDs is transparent, with just a single layer of gray PLA before the symbols start. The base plates were printed in solid transparent material, as I don't have dual extrudes to do a layer of gray PLA on the outer edge of the sloped sides.
I sanded down the sides post printing , and glued all the pieces together. On the smaller version I also painted the edges a slightly darker gray. This was mostly to hide the transparent material of the base plates when the LEDs were off.
I used the pattern from a papercraft Hedron that WOTC had released in PDF form for the patterns on the side of the Hedrons, cleaning them up in Photoshop , and converting it to an SVG in Inkscape so I could bring them into 123D Design. The patterns made 123D groan and hang up slightly , but it was worth it , they turned out great!
The side pieces are designed to be glued together onto a matching base plate. one of the base plates will have two 4-40 screws that fit into matching keyhole slots on the other baseplate, insert the screw heads into the holes and twist to secure!
There are two variants for the side pieces for both the large and small halves, the normal full pattern pieces , and a version that has a rounded corner section. you can mix and match when you print to have whatever combination of sides you want, I personally went with 3 of the normal sides, and 1 with a rounded corner for each half, and then offset the rounded corner pieces by one side from each other during assembly.
