3DPSCO = 3D PRINTED SHOPPING CART OPENERS
Big Shopping Cart Opener Test 2019!
In this big test, I focused on their functionality on different types of shopping trolleys, shops and mechanisms. I included 12 freely downloadable shopping cart openers in the test. Everyone works by plugging it into the shopping cart, the cart opens and you can shop. However, not every opener works on each trolley and this test has been developed. I could only test in Slovakia in five shops. They were Bill, Kaufland, Lidl, Tesco and Cba. In addition to functionality, I tested the practicality, size, flexibility, hardness.
The results will be published 30.12,31.12 or up to 1.1. 2020 :)
But I'll try to publish them as soon as possible. But it's a lot of work to test every single one.
EDIT: more detailed test results will be published soon ...

Last test results:
- The easiness went up to one hundredth of a millimeter, so do not take this result as a priority! However, it was included in the test and the ease of pulling out with the trolleys is the same everywhere except for some exceptions !!!

Test Results:
And we have the test results! Testing was very challenging, lengthy and difficult! Some models surprised at the good but we have also very unsuccessful pieces. The well-deserved model with number 3 came first.
First ! - Model number 3
At first I thought it was another ordinary opener. But the opposite was true. At first it seemed too rude to me, but eventually it was sufficient. what about the ease of picking up the trolley did not stay well here. But I think it will be easy to remove from the cart. I rate the design very well because I liked it very much. And we can not forget that it works on almost all types of shopping trolleys! First place desperately!
Second ! - Model number 4
And we have a second model. The image on the model did not print the best. I thought it would affect functionality but it shouldn't. It worked really well and reliably. Thin is enough so it should be easier to remove. With the withdrawal as well as the first place lost points. Not that it was difficult to pick, but the competition was a bit better. Even so, I think that you will have absolutely no problem with picking. He also lost points on design. I don't know why but I don't like the image of the elevation. But the perfect opener all the time!
Third ! - Model number 11
So this is a full-design design flop. Large piece of plastic reminiscent of a beer opener on your keys. But who does not mind the appearance so for me it is a super opener without compromises. Very easy to pull out. It is solid and works in most stores. Except for the design, it's perfect!
Fourth ! - Model number 8
In a nutshell, it is a small shopping cart opener that works almost everywhere. But the practicality. It is so small that you will quickly slip out of your hands and hit him in the shopping cart is literally hell :). You lean into that trolley with your keys to finally open and when it opens so you will fall out of the keys and to the ground. It's a good opener but for people with small fingers and strong nerves.
Fifth ! - Model number 2
Even if it is long enough, the shopping cart is difficult to open. It does not have a very firm eye so do not expect it will last on the keys for a long time. Works on not all shopping carts. But I really like the design! A golden center for me.
Sixth ! - Model number 1
Such a smaller copy of the two. It's smaller and I don't like design anymore. I must commend that you will not have a problem with removing him from the cart. But the strength here is as violent as the two. It is also less practical due to its size. But still good for me!

Seventh ! - Model number 10
So I didn't understand this. Works on the vast majority of shopping carts. But the hole is too close to the edge and a terrible tear even when it is reinforced. It is easy to remove from the trolley. It is impractical because it is very stretched on the sides of the body but also at the hole. Such an average for me.
Eighth ! - Model number 6
It is the largest so it will be the hardest to remove from the shopping cart. Some may not mind. But the design. No matter what side of the party is weird. And it looks like he could help make it easier to open. Well, the opposite is true. other parameters has an average, it will work in almost all stores. If you don't mind the design and the effort to open the truck is just for you!
Ninth ! - Model number 5
And we have this batman opener! Right at the beginning does not work in most stores which is a great pity. Very but very difficult to pick with shopping carts. Sometimes I thought I wouldn't even pick him up and sometimes he broke. With the key you just don't fall off is strong enough. Everyone has a different opinion on design but not bad for me.
Model : https://www.thingiverse.com/thing:3635087Tenth ! - Model number 12
And we have the last three models. This, unlike the five, works on at least a small portion of shopping carts. It is small and therefore at least easy to remove from the trolley. It's not practical twice, but it may not bother anyone. Although the hole appears strong enough and is far from the edge, this is not true. He is very vulnerable to breakage. But still usable for me!
Model : https://www.thingiverse.com/thing:3382331
Elventh ! - Model number 9
It's very impractical. Unlike model number 8, it is even smaller, so everything bad doubles! I liked the design more at 8. Here's so unnecessary. It is very rare and you are afraid that you will break away and with the keys is very difficult to hit the trolley. But it will work on some.
Twelfth ! - Model number 7
And here's the last place. It is very impractical because it is small. The design is about nothing. It will only work on a very small number of shopping carts. For those who worked and picked quite easily. But it is thin and the hole is too close to the edge so it can easily break. It is difficult to put in the shopping cart because it is very short.
So here's the end of the test! Finally, I just want to say that this was not paid by anyone and is completely independent of the users. The first three places get a seal of quality in their label. Sometimes maybe again.
