Polymaker Hook Tournament: Round 1 Part 2/2
HTML-код
- Опубликовано: 2 окт 2024
- Polymaker is hosting a 3D Printed Hook Tournament.
We invited the 3D printing community to show off their engineering skills and design the strongest hook!
During this single-elimination tournament, hooks are facing each other in a tensile strength contest until one of them breaks or let go. From the qualifiers to the final, only one will survive! However, the top 3 hooks will be rewarded with prizes.

**Spoiler alert** A couple surprises in this one, but I'm mainly impressed with how well the spirals did
Spirals for the win!!! :D
FYI Bracket is posted here challonge.com/PolymakerHookTournament (this was grabbed from their Twitter post). I moved on to the next round somehow, but I never saw my hook or competitor's hook in any of the videos. Also, it seems like the bracket changed because I was not up against XXX originally.
2:00 I'm pretty sure that's not a hook
Here the rules:
- The hook must allow two quick links to attach on both sides for the test (if not intuitive please attach a quick drawing of where to attach the quick links with the hooks)
- The hook must be open, it cannot contain any complete “holes”
@@lukassatas9115 "the hook".
That white cylinder is not a hook, in a hook there is mainly tensile strength.

@@moctezumaCiete the spirit of the rules is not a rule though
@@lukassatas9115 Its even more important, it's the main reason for the contest. A creativity contest about the best way to use tensile stregth. It would not be neceary to say that use mainly compresion stregth or shear strength is not fair.
Can you understant? You cant use an apple in a tomato contest
Quoting polymaker's site:
"*EDIT: 09/18/20 After receiving 2 entries a little bit on the edge of the rules which we have not predicted, we would like to highlight that the spirit of the tournament was mainly around a tensile strength battle. Although we admire the creativity and effort, we will not accept “hooks” which will make the two metal S-hook hooked on themselves since this way there will be no tensile strength applied to the PLA hook
"
So how can#SENDIT_HOOK be considered ok? Experiencing compression forces only!
I think you are right that this hook is doing just that... no tensile trength.. only shear forces.
@marco latn See my reply to AV3NG3R00. They were referring to designs that made the S hooks interconnected. That's not the case here and is totally different. All of the hooks shown meet the rules as specified. They clearly stated "The size and shape of the hook are free". Also, there's another hook that's similar in design. Look for it in Round 2.
ibb.co/R0SGffh this was my entry they rejected that the edit is referring to. Technically within the rules but completely against the spirit of the competition.
The clarification i got was: as long as the metal hooks don’t hook each other it is fair game
@@lukassatas9115 Exactly what I thought. Very clever though! I hope they allowed you to enter a different design.
@@twinturbostang they did. It will be it will be in round 2. Very similar to #sendit
I really love the idea of this competition, but I think the rules should be changed a little to make them clearer and fairer for everybody.
I wouldn't have imagined that anything where the hooks are effectively overlapping - like the white thing at 2:00 - would be allowed.
Also, even though “closure” style designs were intended to be allowed - like the top hooks at 0:15 and 3:30 - I think this takes away from the competition, since these designs are effectively “links” and not “hooks” - i.e. you wouldn’t be able to hook them over anything.
So my ideas are as follows:
1. No closure mechanisms - all submissions must be "hooks" by the standard definition of the word - i.e. you must be able to hook them onto something.
To enforce this rule, instead of using steel hooks as the tethers, use steel chain links or similar. This way no one can cheat - everyone's design will have to be a hook almost by definition.
2. Minimum axial distance between steel hooks of say 30mm
Just a thought.
I think the "open hook" idea is brilliant, i love seeing all the different way people tried to bend the rules while staying within the rules. If its too strict then maybe the hook diversity would not be that great.
"Rule 1" is already a rule. If you look closely, none of the hooks have fully closed loops; there is always a break somewhere. Also, they gave example videos on the contest page of legal hooks that would not work with your chain link test, so the hooks with a locking feature were the intent of the organizers.
I do agree with your rule #2 though. That one at 2:00 did seem a bit unfair.
@@andrewluchenbach I thought there were were supposed to be a hole and it was not connected I do not see a hole at the 2:00 hook.
@@andrewluchenbach I’m aware all of those designs include a break. I understand that was the organizer’s intent, but you can’t call such designs “hooks” because they aren’t able to function like a hook. Additionally, those closing mechanisms are non-functional - you couldn’t open them if you tried. I think the competition would be a lot fairer if they just used steel chain links as the tethers, which would automatically eliminate any sneaky designs.
Edit: right you are though, they do include examples of those mechanisms on the contest page, but nevertheless, I think it makes for a less competitive competition.
I think the competition was all about creativity. And #SENDIT_HOOK idea was genius... The only thing that bothers me is that I didn't come up with it hahaha
Made it through round 1!
Where is Skellor?
4:09 Poor Dio, although it won, the yellow C suffered significant local plastic deformations... good luck in the next round
7:49 wow the loser here is very impressive, with a little tweaking (like a bigger groove for the hook) I think could win
Great idea! But execution could have been better. Maybe with a host or commentator. Very interesting though
Did someone just use An enlarged letter s from a design programs font? Lol
Still didn't see mine going to the test ... strange.
Some were automatically moved to round two if your lucky like mine
@@arcadecarpet631 hope so, took me a lot of experimentation to finally get one I barely could break by hand.
@@skyhacker6 I think several hooks competing do not even flex a bit by hand
I guess mine didn't make it into round one?
Some got moved to round 2 automaticly
@@arcadecarpet631they probably saw that there is a specific design style that would get narrowed down to in the contest. My hook is more traditional but still easily beatable. Maybe they gave me a pass so that they'd have a Cinderella story hook that gets destroyed in the semi finals? ;) J/K mine is gonna get destroyed next round!
Great tournament! Popcorn time :)
Is this all from round 1? Im missing some hooks.. Olias vs Thomas Padula
Would love slow motion of all the breaks
What happened to the original bracket? Did you really have to put me up against Rise3D right away?
Its correct according to the bracket on instagram.. at first their name was in chinese.. but still the same ;)
@@Johan-ul9jb Any chance you are also recording the max force at failure? Would be nice to see a chart at the end of this to see how we ranked.
Im just a participant ;)
@@EricMcCormick ditto- I would love to see strain graphs! Also I’m calling it comes close between raise3d vs cnc kitchen!
