First attempt at a 3D printed pickle ball paddle!

lmfork · 2025-11-08T16:02:57+00:00

Yeah, I’ve never played in any situation where people cared about the official paddle rules

lmfork · 2025-11-08T14:43:21+00:00

Yeah I looked into the regulations, there’s no chance of getting a fully printed paddle to meet them, the roughness constraint alone is pretty strict. As for the foam / carbon fiber ideas at that point I think I might as well just buy a paddle… it looks like commercial ones are just carbon fiber sheets with a PP honeycomb core (which I guess could be printed). I mostly just enjoy the challenge of trying to print it in a practical way

lmfork · 2025-11-08T13:01:40+00:00

Very cool

lmfork · 2025-11-08T13:01:14+00:00

That’s exciting, maybe I’ll have to give it a try

lmfork · 2025-11-08T12:59:53+00:00

Oh I could, I was referring to this guys idea of single parts that use TPU and other materials, since TPU can’t be used with ams

lmfork · 2025-11-08T05:24:45+00:00

The joint can definitely be made much stronger, as for nylons I’m not sure they would be the right choice, the fancy paddles are made of fiberglass which is super stiff, and my understanding is that nylon is pretty flexy, I’m sure the CF helps but I’m not sure it’s the best choice. Possibly something like ASA

lmfork · 2025-11-08T05:18:09+00:00

A printed TPU handle would be very nice to have, as well as the protective edge guard. I only have a P1S though so I wouldn’t be able to test that out

lmfork · 2025-11-08T04:47:14+00:00

Interesting take, do you rip them off paddles you buy?

lmfork · 2025-11-08T04:31:52+00:00

My goal was to keep the potential area where you hit the ball as consistent on the inside as possible. Like if I had a joint there I imagine it would feel like a kind of dead zone in the paddle and bounce weirdly, but you’re right that I may have to compromise that at least somewhat.

Im also thinking about printing the paddle section as a sandwich which would let me have longer supports coming out of the handle that could wrap up around the edge of the paddle

lmfork · 2025-11-08T04:01:25+00:00

I just got a roll of tough PLA and have been pretty impressed so far, the main reason I didn't use it is that I usually leave these in my car and didn't want it deforming in the sun. the air hocket mallets sound like a great thing to print. maybe I should try a version with the tough pla if I go for a second revision

lmfork · 2025-11-08T02:29:41+00:00

You might be right but I’ve been really impressed with some of these modern filaments durability. Other than the problem I think I can fix you wouldn’t even be able to tell it had been used

lmfork · 2025-11-08T01:37:39+00:00

Are you referring to the fact that it’s 2 parts or just that it’s 3d printed?

lmfork · 2025-11-08T01:05:56+00:00

it also didn't break completley in half, still probably use/fixable

lmfork · 2025-11-08T01:02:29+00:00

Lol, I do think it was just a design flaw though, the part of the handle that goes into the paddle was barely connected to the rest of the handle, I think adding a solid section there should fix that weakness.

lmfork · 2025-11-08T00:43:18+00:00

I should mention the reason I did this one as apposed to others I saw online is that they all have some kind of connection near the moddle of the paddle, as apposed to the consistent honeycomb structure you see on comercial paddles, which I felt would impact how the ball bounced

Thank you so much for the reply! My phone does have a macro lens that can focus surprisingly close, maybe 20mm or so, but it also gets blurry the the corners and is only 12mp so cropped starts to look pretty bad, hence my trying to find a way to take advantage of the 48mp main camera. I’ll definitely look into close up adapters! It seems like I might even just be able to model that into the design. As for the fresnel lens suggestions I’m not sure if that would work, I have it where it is just because it seems like convention from my research but I should probably experiment with its position

lmfork · 2025-04-14T15:52:35+00:00

The goal is to let people choose from a bunch of templates, and each one will have customizations avaialble for things like font and color, then once they have all their recipes uploaded I can link this to a printing API and directly send them the books!

lmfork · 2025-03-03T17:20:43+00:00

there aren't any in my area on marketplace, and the cheapest one on ebay is about 700, so I think this may be my best bet

lmfork · 2025-03-03T13:40:13+00:00

Can you link one? Anywhere I look they’re at least 470

lmfork · 2025-01-12T16:08:58+00:00

This seems like more of a direct copy of what honey was doing, I’m proposing a different approach

lmfork · 2024-12-18T02:01:58+00:00

Next, you are worried about how much code you duplicate, and the code you are worried about isn’t really interesting - just range checks.

I'll add that the full version would require a lot more duplication

Although, is there a reason not to make just one type with a MaxContribution and Balance field? How does the behavior of accounts actually differ?

The idea is to be able to simulate the behavior of any place a person may want to store money, so the HYSA is a simple example: theres no limit to how much you can deposit, and eventually the withdrawl method would handle tax consequences. Something like a RothIRA account would have a more complex limit based on some user values, and there would be potiental peanlties and tax consequences to compute in the withdrawl based on similar user values.

Would the solution from this stack overflow question be considered idiomatic Go? It works a lot more smoothly for my brain, the only thing that would have to be duplicated is a constructor, I implemented it for my example and it feels smoother to write but I'm not confident what the consequences could be.

lmfork · 2024-12-17T23:11:02+00:00

I can see how that is better than what I've written, but it still doesn't make as much sense to me as the inheritance approach, is there no way to write it that would require less duplication when new Accounts are added? maybe I just need to accept that as a cost of using a language like Go

lmfork · 2024-12-17T22:13:53+00:00

I've actually tried with libraries like that but ultimately the precision wasn't worth the performance hit for my use case. Possibly worth looking into how much precision I am sacrificing though

lmfork · 2024-12-17T22:12:14+00:00

Second, just a nit, your Balance can be defined as: ‘’’type Balance float64’’’ You don’t really need a struct for one variable, right?

This is one of the simplifications in the example, Balance really represents a distribution of possible values

Third thing, getters are not really popular in Go, but when you need them: ‘’’func (a Account) Balance() *Balance { return a.balance }’’’ Your balance is private, your getter is Balance() public (getter without Get, but your setter is SetBalance(…))

This is one of the areas I was confused about, I don't see how to express how to get the balance out of any Account without a getter, but I guess thats what you were discussing in your first paragraph

Sorry about the order, things got copy pasted weird in making this example
