3D printed pool cue

Piece 6 and 7.

It looks and feels great IMO! It is solid and heavy. I added a chamfer between the sections to both print better and hide any mismatches better. PS, I just bought this new Predator cue with Revo 30" 12.4 shaft. I absolutely love it. I've had it a week, but not been able to play it yet. Hopefully in a few days. I'm at my dad's house for the winter and don't have a pool table here.

The joints seem very strong. I was going to break it today over my knee, but I think I will keep it intact, maybe do a break test another time.

It is super straight! Within .0015" sweeping the whole bottom low point. I couldn't believe it.

The face of the joint is very flat. Within .001" all over.

The top of the part is low by .030". I guess the layers shrunk in height. Not a big deal for this, and I'm not going to mess with the printer settings to try to improve. I'm scared of making it worse. I'm printing another piece now (piece 5), and I left the door open on the printer. (I always keep it closed for the noise). I will see if that makes any difference to the height.

Here is the height it's supposed to be, 8.375". The indicator has spun one complete revolution.

Another idea is to make a cane and put the shaft in the butt. I travel through airports in many countries. A cane is allowed onboard a plane. It needs to be X-rayed but since no weapon is inside the butt or shaft it will pass. Then you have a two piece cue. Make the butt out of heavy metal to make up for the weight. Also, no airport in USA or Europe requires proof of disability. No cane is required to be airline approved. If I walk with a baseball bat as my cane if should not be disallowed. I have been disabled for 5 years and gone though about 12 airports so something to research. I've used a variety of devices as canes.

I was thinking about this a couple months ago. To make the cue hollow and slide the shaft into the butt, since its tapered. I didn't go further than just a thought in my head though.

Very interesting about the cane. Thanks for the info.
 
I have a new plan, to test this out quicker. I'm going to print all the pieces that make up the back 30" of the cue (the traditional butt). Then print on the frontmost piece a 5/16-14 thread and attach my predator 314 to it. This is only a test to see how the butt feels when I go play pool this week, using at off-the-shelf 314 shaft. I expect the 5/16-14 thread to break. I don't have a 5/16-14 pin here, I think I have them all at my house in Atlanta (I'm in philly now). If I did, I would print a female thread and put the 5/16-14 pin inside.

Those are some great results! Did you model your parts in Fusion?

Piece 5 just finished. The filament ran out near the top. IDK if that affected the height accuracy at all, for comparison with the prior two pieces. This one is .007" taller, or about .023" below designed size. I'll try the next piece with the door open again to see if it does anything.

Here is the completed back half. The red piece at the end is just to try it with a full length 314 shaft. I kept it short, so I can print 3 of them to take to the pool hall, and if one breaks, just swap another one in. The 4 other pieces are the real pieces for when I modify the 314 to cut it at 16". So they won't go to waste.

Adapter design. The threads got clocked in the CAD, too much hassle to correct, and won't affect anything.

Whole rear end. I need to weigh each piece to see if the calculated weight matches the printed weight. Then I can add hollow areas to adjust balance and overall weight. I'll do that on the next one I print. This is good enough for now.

That is some dialed in stepper motors and extruder for those tolerances!!!

Based on the orientation of the print....If I was to bet....My bet would be it will break flush where the threads meet the butt....been down that road with threaded prints........to add some strength to threads.......don't thread all the way to the bottom leave a few MM of unthreaded rod and add a small fillet between the threaded rod and the face....(add your corresponding space and fillet to the inside of the female threads) ...It will still thread all the way face to face.

I was going back and forth on doing this when I modeled the threads. When I had them hand sketched I had a thread relief area. I added it to the new pieces based on your feedback. I think this is a bit different than the way you suggested, but it should have similar effect. The thread helix ends below the face of the joint, then it has a full round. This is on the two front pieces I'll be printing soon, and the two back pieces already printed are like the first picture. We can see if it makes any difference if/when I do a strength test. I don't know enough about the filament bonding to know if a radius on 3D printed parts has a similar effect to reduce stress risers as other manufacturing methods.

After (ignore the thread clocking)
 
I'm pleased as punch as Earl/Rogan would say:) My first cue. It took me 27 years. I got my first metal lathe in 1996 and all my buddies have been asking since then when I would finally make a cue. ha ha.

The butt all screwed together is definitely flexible. I think it might still work though. I will take it to the pool room tomorrow to hit with it.

If everyone is bringing their own custom cues to the pool hall,

then when are the professional cue makers going to up the customization game?

Fabricating your own cue, means you can start housing custom electronics discretely.

There are alternative materials to use as well. For builders and anyone that goes to Home Depot.

I want a McDermott that partners with Texas Instruments that meets IEEE standards for special radio devices. There is a lot of sensor sponsorship that the chip manufacturers can provide at low costs, you have to sell them.

I am shopping for a Cuetec that has a storage space in the shaft for a 12V power supply.

Make your product marketable at their level.

Pretty sure you wouldn’t pass a Turing Test.

Back in the 90s internet was highly promoted in US elections. Today it is a standard.

Pool has new standards, the number of cues to own today is a lot more than it used to be.

Printing your own equipment for pool can be the new revolution the home made revolution. Fast prototype, fast build, low cost designs this means engineering is going to be popular in pool. Pool can achieve the tech tree for electronics, its time to update everything.

The forum might need a tech support section for 3d users or software designs.

The need for better pool luggage is also important. Pool players travel and quality luggage helps.

Take a shot at me. I practiced against early prototypes of the AI natural language processor, there are clear openings to take advantage of in paradox questions.

Ok. Describe why time flies like an arrow but fruit flies like a banana.

Cosmic forces are pure and constant. Biological structures are governed by internal forces as well as external forces, in short biology was designed for decay, while time was meant for eternity.

I am interested in positions that will pay for my security clearance and relocation.

I dont post technical for fun. I am looking to be hired.

How about this old classic, can an all powerful being create a rock too heavy for itself to lift??

Or maybe get into moravecs paradoxical goodies?? That might get you some interest, if you post it in layman's terms.

I do the scientific networking because I want to get hired.

Posting those in layman's terms is considered a paid gig.

Are you a recruiter or capable of direct hiring? I can do both consulting and teaching.

Gotta loosen up on those 'paid' 'unpaid' gigs around here if you want cred bud. Just a thot.
