3d print raquet extension?

pointbreak

Rookie
Hey huys... I have an extended pro stock and would like to extend a prestige now... Just bought an Xl Flexpoint but Microgel is next, anyone tried a 3d print? Should be easy to fix? I am making some molds in wood now to start off.

I printed extensions which I glued in the hairpin, and than cut new pallets to correct length. But my preferred solution is printing extended pallets with build in extensions for head rackets. Used this with success up to 1 inch of extension:

Trying to follow... you buy an extended pallet and you fill the gap in the extension with glue?
Sorry, I see that I didn't articulate that well.
If I just print extensions, i glue that in the hairpin and than buy new original Head pallets to mount on the extended hairpin and cut them to length. But my preferred way is to just print pallets with extension build-in like in the picture i posted.

Ooo, Any recommendation on a printer for the task?

Epic! I will also use and extended TK82 palett=)

Is impacting tennis your channel..... Just checked it out, good to see you posting back after years. I never unsubscribed it

I dont 3d print...but I'm surprised the people who do this haven't shared their files.
Here are some resources that can probably be modified:

I went to a local uni to try and get an extension printed but they haven't been able to complete it so I am looking around for other options...baffling to me because they offer print services but little CAD work.

Looks interesting. What grip size are those extension designs for?

I made some extensions from a broom shaft today=) Just some old fashioned tools and sandpaper for the right shape, sawed a line in the middle so it will click in fine in the hairpin and then I just saw them off in the right length... Then on with the new extended TK82 pallet... Someone should really start selling something 3d printed=)

I used to do something like that too.

It's possible that some people share their 3D drawings for free. These are the hippies among the creatives.
They live off air? :unsure:
I share a drawing worth the equivalent of €200. I'm still one of the cheapest in the league. Have you ever looked at what unstrung customs charges for its prints?

I mean a pallet is an octagon extruded to length. It's not a particularly fancy work of art.

Again, this an area of tennis that I have no need for. If someone can charge €200 for a custom pallet, and someone is willing to pay for it, good for them.
I didn't realize the market for this space was this expensive.

You can get a 3dmakerpro for $400. So with that you could scan as many rackets and hairpins as your heart desires and modify them to ones needs. Just a thought in case someone wants to combine their love of 3d printing and tennis!

Well, I have no idea how deeply you have read into the matter.
I would like to point out that I don't draw octagonal things, but the inner hairpin including the recess for the logo and the exact dimensions including the end cap, and all in one piece.
If you take a closer look, you will notice that the workpieces shrink by a few tenths of a mm - this depends on the density, the material and the temperature.
You have to take these things into account when drawing, otherwise you will end up with a part that you can throw away after 4 hours of printing.
As I said, only with the 3D drawing can you slice a printable version in the printing program of the 3D printer and then print it.
I ONLY charge this initially high amount for the drawing - if you print 20 of them, the unit price is negligible.

I don't think the result will be a disappointment.

The print has become super bad - he doesn't have much of a clue.
As I said, his program can't take into account the shrinkage of a few percent.
It then only has the outer contour - but you also have to measure and draw the inner contour of a tennis grip.
The guy can't do that with photogrammetry.

I didn't mean to imply what your doing is minimal. You're clearly do more beyond what I was thinking as essentially printing 2x of a traditional half pallet and stapling it to the hairpin, installing a buttcap traditionally, etc. As a non printer, I am not savvy to the intricacies of the materials, shrinkage, type, etc.

There's certainly a luxury that can be done as you have done, with integrated buttcap, "perfect" for to the hairpin, and potential for weight customization.

I meant to imply that it could be done "good enough" for most people relatively cheaply. Half my clients play with shredded grips and overgrips....what you're doing is above and beyond what any of them would appreciate/notice.

I presume you glue/epoxy your prints to the hairpin?

Just tying to show what could be involved in creating the files and printing. The local D1 college near me has a 3D Print lab I could use and courses to become an expert. Can’t be too hard.

Yes, the finished handle is glued with 2K and holds bombproof.
By the way - you can always make things simpler and lighter.

But it's not always reliable - I don't want to play with a grip that gets crushed on impact because you've skimped on the layers.
If a handle is made from 3 parts, there are weak points that are not necessary and can break. On this occasion you also have to keep an eye on the new total weight.

I had to constantly re-tackle the end caps for some players because they kept creaking.
That's impossible here because they're one piece.
I also draw half grip sizes and conical grips.

Some people spend thousands of dollars on new aluminum rims for their car - steel rims would do.
Everyone should spend the money they get good value for.
For some it's worth it, for others a shrink sleeve is enough.
It's as simple as that.

Yes - please do a course so that you can show us everything in detail.

At first, when I started making 3D pallets, I thought it was simple, but there is also science behind it. Each brand has a different hairpin that generally has variable dimensions throughout the length and width. Only when you make the first printed pallet that has uniform dimensions across the entire width and height do you see how much work there really is. After making the STL, you need to know how to print the pallet so that it does not crack or flatten after use, as it must be light and cannot be made of a full profile. People pay for racquet stringing for 30€ with strings every 5-10 hours of play, so I don't see why someone should make pallets for the same price that last a lifetime on the racquet. By the way, a deviation of 0.2-0.3 millimeters in height or width is really felt on the racket.
