Hi, this is such an awesome design. But, after printing I find the parts are very tight. This particular part broke apart in my hand when I tried to adjust the gripper arms. I'm sure you have answered this before, but any tips on getting them to fit together better? Thanks
Hey, we're glad you like the design! We had to rely on fairly tight tolerances for the Gripper to fit everything into one tile. We've been designing a couple of alternative versions that have more forgiving tolerances, which are now available in the Optional Parts zip folder (the downloadable files have been updated).
The problems everyone is having are not being addressed. This is the first time I've subscribed to Thangs, and because of you it will be my last. The tolerances are too tight and you have done nothing to fix it. Just taking peoples money.
I have had some trouble with this print, but after some experimenting i have found the key to be:
printing on a raft
high infill
working the mechanism back and forth a few times with some silicone lube before installing it on the rails
It seems like we are all having the same issues with not being able to loosen the gears without breaking the tabs. Is this being looked into or are there any solutions?
do not bother having loose gears. even if you do not have tolerance issues, the very small connection between the mechanism at the back and the hooks at the front will break very soon. and if you try to glue it back together, everything becomes static - so what about the purpose of a variable hook width, then? in my opionion, nice looking try, but much room for improvement left. let's see what they will come up with.
Hey! We've been working on two alternative options that have more forgiving tolerances. We've updated the downloadable files and you can find these two versions in the Optional Parts zip folder.
after 3 times printing and trying to get this hooks moving, i give up. too tight, no chance to loose this thing, so it'll move nicely. imho it's not a good idea to place the moving pieces at the beginning of the rail.
Finally i succeeded to print the Gripper and to loosen the gripper arms....
i managed to do this, right after printing, lets say, waiting for 2 or 3 minutes i startet to loosen very gently the gripper arms. with this way i succeeded to release them without breaking them.
maybe it was also the filament or maybe both.... i used polymaker filament...
so maybe this is for someone helpful who did not yet succeed printing and realising without breaking.
Hey, thanks for the updates. The Gripper does rely on fairly tight tolerances to fit all the parts into a single tile - we're glad to hear you got it solved in the end! if you have any issues in the future, we have added to alternative options which have slightly more forgiving tolerances.
Hey! We've added a couple of alternative versions that have slightly looser tolerances and are more forgiving to print if the original design isn't quite coming off the printer smoothly. The downloadable files have been updated, so you can find these two versions in the Optional Parts zip folder.
Guys! This is not a tolerance issue.The carriage is guided at the front but not properly constrained at the rear. When users adjust it, they apply force above the sliding plane, creating an overturning moment. The carriage tilts, side-loads the rails, friction spikes, and the mechanism binds — then parts break. Pressing the back against a flat surface removes the tilt and it slides smoothly, which confirms it’s a constraint issue, not clearance. Send me step-files. And I'll gladely fix it.
So far this is the only part of the cargo connect system i've had any trouble printing, all other parts print perfectly woth no supports, rafts or brims at all. I did manage to get the release version to print correctly but i had to slow my printer down, lower layer height to 0.1mm and add a raft to just keep everything perfectly in place.
All that being said I have the larger tolerances version sliced and ready to go so ill keep my fingers crossed for that one turning out well.
I became a member more because of this part, but out of 6 attempts I was successful in only 2, I noticed that the gear that broke always gets stuck either on the rail or on the other gear, are you seeing an improvement in this part? I realized after I became a member that everyone has been having the same difficulty for months and no one responds.
Hey! The Gripper is probably the most advanced Cargo part to print - we had to rely on fairly tight tolerances to fit everything into the tile. We’ve now added two alternative versions designed for easier printing across a wider range of printers:
- Grippers – Larger Tolerances- Manual Grippers – Larger Tolerances(Full info is in the User Guide)
The downloadable files have been updated and you can find these two versions in the ‘Optional Parts’ zip folder.

Same as everyone else I'm afraid, the cog seems to be unable to rotate so the adjustment mechanism does not work, which is a real shame and needs fixing as this system is why me and lots others are paying you. AnyCubic Kobra 1S

In image 3 and 4, the sliding grippers have their own sets of "clips" to make them act as a tile, and not need the extra tile on the back. In the stl, the sliding gripper only has 2 notches and no prongs. Could this perhaps be addressed, so the gripper is able to act as an independant tile?
Hey, there are two versions of the Gripper included within the files:
A 'fixed' version with the connections on all sides - this model can be connected into the wall, but does not slide on the rails. (More compact and less filament for if you just need a fixed setup)
A 'sliding rails' version - this model clicks onto a sliding baseplate to make it compatible with the rails. (Slightly thicker and more filament, but great for the flexibility of the rails)
The grippers are not supported by enough material to make them usable. The grippers need support on both sides and thicker supports that connect to the rack and pinion. They cannot handle gentle misuse. If you grab a part incorrectly, they shatter. As such they are not going on my shelf.
I wanted to love these,but they are a waste of filament.
The second one I treated with great care, but it gets stuck and bends.
Have sum suggestions, maybe you would take them into consideration. There is an interesting mechanism on a sailing yacht for clamping a rope in place. It straps any rope of any diameter. I think it is called a cam mechanism.
I made a sketch of a potential mechanism. If you will make it I would love to buy it.
+1 to the other requests.
I also request a high tolerance version of these and the hooks. I'm still learning, and PETG is fusing to itself on the base of the hooks and basically the entire mechanism on these. PLA sometimes works.
The layer lines are oriented in the same plane as the direction of movement when adjusting, which makes it very susceptible to failure on the layer boundaries. I suggest making the grabbers separate snap-in pieces that connect to the adjustable carriage.
Please add the missing PDF file with instructions on printing as mentioned in the description.
Also wondering why you removed my previous comment with the same request?
Thanks for letting us know. The 'User Guide' was uploaded by us with the original files, but seems to have been removed automatically at some point by a technical issue. We have re-uploaded this to the downloadable files, please let us know if it still doesn't appear for you.
Unfortunately we haven't seen your previous comment, but we haven't deleted or removed it from our end.

Definitely to tight, to move the gripper. Printed in petg-cf and after the first slide, the slider just broke off

Same here the design is not working, If you want to adjust the grippers it breaks. I printed in PLA (Bambu) PETG (Generic)
Please adjust the design, its a great addition to the series

Nice design before printing. 4 tries everey Part ist breaking. It´s too tight designt. It´s not working.

Would these be able to hold a milwaulkee 12v tool like the impact driver or drill, without the battery?
Hey, no the Grippers aren't designed to hold larger items like power tools.
I became a member more because of this part, but out of 6 attempts I was successful in only 2, I noticed that the gear that broke always gets stuck either on the rail or on the other gear, are you seeing an improvement in this part?

Can not get this one to work. Prints great, but like with most everyone else the gear in the middle will not move.

do we actually need to print any support for all the cargo modular system here?
Hey, the Cargo Modular System has been designed so far to not need any supports when printing.

Thanks man, that's my bad. I thought "fixed" was referring to the gripper arms. Upon slicing, I quickly realized my mistake.
The grippers are not supported by enough material to make them usable. The grippers need support on both sides and thicker supports that connect to the rack and pinion. They cannot handle gentle misuse. If you grab a part incorrectly, they shatter. As such they are not going on my shelf. I wanted to love these,but they are a waste of filament.
