Hey everyone:

If anyone owns the Gretzky table hockey game with the accessory pack that included the benches and glass boards, then you may have experienced a broken bracket or two (as I did) when you had to box the game up. 

So in my search for a replacement, I had a couple options: track down a replacement on Ebay or try to recreate the bracket in a modeling program and fabricate it on a 3D printer. So I chose to model the bracket and fabricate. I had never modeled anything for 3D printing before, so I gave a program called Sketchup a try. I used the online free version that runs in the browser. 

Took me a few hours to learn the application and model the bracket. Since I didn't have a 3D printer, I went online and outsourced the print. The result was pretty impressive. My model was fabricated using white ABS and the finals were near identical to the original.  They had a little more flex to them, which might make them less prone to breaking when they are removed. Below is a photo of the 3D prints of the 4 brackets that were fabricated.  

Thought I would share in case anyone has thought about 3D printing some custom parts for their games.

Fantastic post!  I was was thinking about doing this very thing.  I have a few of these games that I use with the students in the Table Hockey Club I run in my school.  Every time we go to put the games away a bracket snaps.  Thanks again for the post.

Thanks. Yeah these brackets do snap easily. These ones that I fabricated seem to have some better flexibility than the originals. I've only attached them once, but they seemed to go on and come off a bit easier.

I can make the 3D model available to anyone that wants it. I would prefer to open source it in a way that allows anyone to fabricate it themselves, or I could just fabricate a bunch of them and sell them to anyone that wants it. Any suggestions?

Hi Chinook,  do you still have the 3d model available?  are you still willing to share it?

You bet. Here's a link to download the .stl file I used when I ordered from 3Dhubs. The end result was great and thee brackets have held up pretty well. These were printed on a Folger TEch FT-5, using White ABS with a layer height of 200 μm. Let me know if you need a different file type and please share some pics of the finished prints.

that .stl file should be perfect!!   You're a real sweetheart Chinook!   i'm wondering how well they will hold up if I print them in PETG.. i don't really have any abs..
