A buddy bought another Judge Dredd and came to me to help fix some nagging issues with the dead world mod. It had a lot of worn parts in that dead world section, including a broken out crane cam at the set screw insert. Since these are unobtainable, I mentioned we might be able to epoxy the broken set screw area, but had one other long shot thought. I wondered if it could possibly be 3D printed. I have another buddy that does a lot with 3D printing for a large computer company and I had finally gotten him to come to TPF last year. So I ran this issue by him, took him the original part and he started taking measurements. That evening he had a nice rendering on the PC and within a day or two was printing out some tests. There were some kinks to work out, but in the end, he was able to 3D print a really good representation of what I brought him. We did not have the brass insert for the set screw, but instead had it threaded into the plastic. I was concerned if that would even work without breaking. Last week I installed it on my buddy's Judge Dredd and was able to tighten it nice and tight. So far it's holding up fantastic.

His job does require some intermittent travel all over the nation, but after some thought, he gave me the go ahead to post and see if there'd be any interest in more of these. He said he'd make more for $35, which includes shipping. So, I'm gauging interest. Please let me know if this is something you'd be interested in.

Sounds good. I’ll tell him to get some going.

Quoted from aeonblack:

I'd love the .stl file so i could print my own!

Not my file to share, nor my expertise.

Quoted from tacshose:

Yeah I’m not sure why the $35 just share the file with the community...

James spent a fair amount of time working on this & tweaking everything. Oddly the positions of the tapered sections & screw hole would change positions during prints. The diameter of the holes changed too as it cooled. He made several of them before getting it right. He’s a good family friend & I still wanted to pay him. $30 plus shipping is what the old part used to cost when you could still get it & I, as well as the owner of the JD, were happy to pay it to get JD running again. James asked if others might need this & if he could maybe make a few bucks in the process. Can’t blame the guy for wanting to be compensated for the effort.

If you’ve already got a 3d printer, get a caliper, start measuring your old one & make a file. Print it, tweak it until it’s right & you’re welcome to share it with the world.

Quoted from PinRob:

PinBits was $30 but they weren’t the only retailer with the cam. Marco had cams in stock more recently than PinBits and they weren’t $30. I believe they were around $18 plus shipping. $35 is in my opinion a lot for it but being nobody has any the market is in a corner on price.

Fair enough. I simply knew the last one I was able to find & buy was for $30 plus shipping, so I happily offered $35. My buddy’s JD was down for months while looking for a replacement cam.

Let’s face it, unless you’ve got the Dead World Mod, this part isn’t used or needed. I’m sure that’s why it’s not remade & in stock any place.

With 6990 JD made, maybe we can convince all those not using to Dead World to remove their cams & offer them to the community.

Quoted from Boat:

It's nice to see community created parts.
Another suggestion to your buddy might be to just release the STL and documentation/parts for free and suggest/take "donations" via paypal. Not everyone may have the same price in mind for a part they may or may not use.

This is also true. I did mention to him folks asking for the file & maybe doing something like that. Mentioned it to him again & he’s going to think on it.

Quoted from ArcadiusMaximus:

First off great job resurrecting a defunct part. I understand where people are coming from, but he shouldn't have to give it away for free. People charge all the time for 3D printed mods should those files be given away too? Maybe consider selling the part through shapeways or something similar that allows the user to specify the type of material. It would be cool to print these out of metal ! A few people on here distribute their parts in that manner.

Appreciate the info. First I’ve heard of that. I’ll pass this along to him as well.

Quoted from Dayhuff:

I remember someone about ten years ago making them out of aluminum, pricey but you didn't have to worry about the set screw getting stripped or the piece cracking. Whatever happened with that supplier?
John

I believe you’re thinking of the opto interrupter for the Theatre of Magic trunk. There is a somewhat similar looking interrupter on the planet motor.

To the best of my knowledge, the crane cam has never been reproduced. That makes sense too since it’s unused & not needed, unless you’re running the Dead World mod.

Quoted from Dayhuff:

Hmm.....you could be right, it was a long time ago. After this many years in the hobby I think I've forgotten more then I know at this point. Anyways, thanks for keeping the JD's in the world running.
John

I feel the same way sometimes John. Just glad there’s technology out there & smart folks to use it that can make some wishes like this come true.

Quoted from swinks:

here is a cam I did to help a mate for TZ / BOP
and works out to be around the $35, so a fair price, custom colour and solid nylon

Looks great, good work. I have mentioned Shapeways and he already knew about it. He's got other non pinball items that he's been looking at putting on there. So I guess at this point, he's in the stage of trying to figure out which way to go and getting it all setup. I appreciate the insight on tagging it under pinball though. I'll pass this all long.
