Printed great using the 3mf. The magnets were tricky to get in at first but once I got started and figured out the best way for me to do it, it really flowed. I love how these turned out and work
That looks like it got pretty fused together. Likely from "elephants foot". you'll need to cut it out with an exacto knife. in the future, see if you can get that elephants foot to go away! (many tutorials online)
Tilted when carrying.
Initial print was fused together on bottom and top, not separable, using Bambu Lab X1 Carbon, Bambu Lab PLA Matte White, door/lid closed.
Printing again (GST3D PLA+ White, open door/lid) gave me an articulated print (see picture). Magnets had to be forced in and caused slight bulking of the thin wall.
Generally result looks good, but is not working too well. While carrying, there is a noticeable tilt (picture shows the carrier being held still in the air). This is due to the hair pin not being above the center. In the "official" pictures, the hair tie seems to be closer to a point above the center of the tray as it is in the printed version (as also noticeable in some of the other images uploaded here), where the hair tie is significantly offset and way closer to the border than the center. This means any cup can't be too full as it would swap over. But then one could just carry the mug by hand ... Not sure where this discrepancy comes from, this can't be a scaling/shrinking/whatever issue. Is the hinge supposed to lean further out? (not possible on my print as there is not enough clearance, the picture shows the max already)
Hi, I’m happy you figured out what was causing the fusing to happen. It is generally a good idea to keep the printer vented with pla to prevent the filament from getting too hot. As for the hair tie issue I’m unable to see it in the picture as it is cut off for whatever reason. From what I can see in the picture it looks like there may still be a small amount of fusing going on that could cause the carrier to not fully bend to the angle needed to hold the cup.
I’m having issues with the magnet holes as well. Even for a press fit they are too small. I managed to press one magnet in and it deformed the magnet hole and nearly split the plastic. Are you able to look at the file and adjust it maybe? Tolerances everywhere else are perfect it’s just the magnet holes
I tried to print with my trusty old Prusa MK3S+, but first time I had adhesion problems and print failed.
Second time was much better but the joints are crunchy and don't work well. The hinges have fused together a bit. And the shark-fin pieces and slots, did not really work out either.
The whole mechanism printed awfully, when moved (have to use both hands) makes sounds like old person joints from some cartoon kids show.
Trying to print now newer printer, hope for the best.
I have managed to print on another printer, it is now much better. But I must say that I am rather disappointed with the model. The joints are still too stiff, and the tolerances too tight. The chain-link handle never does not wrap around the base on the first try because of the stiffness in joints and accumulated error causing the joints to not align with their relative slots in the base.
The sharp edges also do not help at all. Some chamber or fillet (rounding corners) would help a lot. Also taking into account the inaccuracies in the chain-link and accommodating for them in the base design.
Lastly, the 90-degree mechanism hidden in the base is unnecessarily over-complicated and always gets stuck because of too much freedom of movement and too high friction. Instead of this weird offset shaft thing, I would personally just used straight shaft with only 2 contact points - the though-hole at the edge letting the shaft go out of the base body, and cap at the dead-end, to reduce the friction.
Hi! Thanks so much for all the detailed feedback, I really appreciate it. I’m glad the second print came out better, and your notes definitely give me some things to think about.
Sorry if it comes off to harsh. I really love the visuals of this model, and put in a lot of effort to print it correctly. So there is a lot of frustration on my side. So sorry about that.
I am more than happy to provide more detailed feedback and suggestions, if you want.
I really love the idea and design, but am struggling to print without the hinges fusing. Is it possible to increase the clearance between the parts? If using magnets, any play given by using more precise printers should be fine while then also allowing for slightly weaker setups to print as well.
There’s a normal amount of play built into the tolerances of this model. If you’re experiencing fusing, I’d recommend double-checking your filament settings, as over-extrusion or material expansion could be the cause. Getting your printer dialed in more accurately will help prevent this issue in the future as well. I’d be happy to share a few tips if you’d like.
hi i want to ask does having another brand of printers affect the file?
i have a creality k1c and the print came out good but all the functional parts are not smooth.
it came out rough and the handle was warped.
i printed as instructed too.
I don’t think support is recommended and you really don’t need it, support may just clog up the handle and other parts particularly the hair tie hole. Try reprinting without support and see if it works.

Why is the magnet holes are 2.65 mm when the recommended magnet is 3x5 mm? Could you modify the model to accommodate 3x5mm magnets?
The gap is undersized so that the magnets are pressed into place and can't come loose.

I made the slots for the magnets slightly larger. I hope that helps!

That printer should be able to print this model. It sounds like there may have been an adhesion issue. Make sure to have a clean build plate
The handle does not fit into place.
Is it locking up? Tilt the handle slightly inward before collapsing and it should collapse down nicely
I think there is support inside so it doesn't collapse
I don’t think support is recommended and you really don’t need it, support may just clog up the handle and other parts particularly the hair tie hole. Try reprinting without support and see if it works.
What is the difference from the other one?
This model can be printed with matte pla, and does not have wood texture. It saves a bit of print time and changes the look quite a bit!
