WILL THIS SURVIVE? 3D Printed Cup Holder on the Himiway Cruiser Fat Tire E-bike!

The @HimiwayBikesLongrangeEbikes Cruiser is an e-bike with pedal assist and FAT TIRES. The cup holder holds coffee. WILL IT WORK? This is my review of the Himiway Cruiser, and the 3d printed cup holder. Himiway provided the Cruiser for review, and Printables provided the files for the cup holder.

Super happy for you. I have a bit of experience with the Himiway Bikes. I wouldn’t say they are the highest quality, but they are far from the lowest quality. For the money, probably the best economy fat tire bike you can get.

Support is pretty good. My buddy had a motor go out. It took a little while, but they sent all the parts for free, with very little hassle other than a video of the problem.

I myself ride higher end Full Suspension Mountain E-Bikes (Haibike), and like you, I’m super excited to be able to ride distances again.

The assist allows me to exercise much longer than I would in a standard bike. I’ve had two heart attacks due to another health issue, and riding these bikes has given me my life back. 👍

[widgget]

yes, print orientation was a major factor, but still could have been accounted for if you had you printed those with more then 2 walls and 15% infil, no wonder they broke.
PLA+ would have helped too.

[freestylekyle]

So I’ve designed and print many mounts for my bike, my take any PLA is a no go, to bridle Fillets are absolutely mandatory on everything that even approaches a right angle and aggressive Fillets. At that all the breaks from the micro vibrations occurred where two faces intersected into a right angle or Near right ankle, I did switch quickly to 100% infill. but the silver bullet that takes it over the win for me was nylon. The vibrational stress is no joke. I have thought about experimenting with vibration dampeners with TPU but after filleting everything and printing in nylon all my prints hold up even, years later years later that is after

[silentpaw]

If you want to try the cup holder again, I'd suggest printing the clamp and holder separate then using a bolt or two to hold it together to get that extra strength.

For other things, maybe a Holder for a tire pump and a small repair kit if you get a flat on your ride. something to hold your phone if you need directions would be nice too.

[TheDarkPreacher]

Maybe a multi cup coffee carrier that attaches to the back of the bike, so you can make coffee runs for the whole family or crew? And maybe a custom printed TPU cushion to put in the bottom of the cup holders to give a little shock absorb pad?

[TheEragoon]

The reason it didn't manage to keep the coffee cup stable is the high center of gravity. That kind of a system requires all of the weight to below the pivot point, aka support should be longer then the cut height.
A resize of the part that hold the cup (make it longer) should fix the issue. Good luck next time!

[grantdeisig]

Wouldn't hurt to beef up those perimeters either. I've tried a few of these and I always end up going back to a fixed holder. Lol

[AndrewSink]

3D printed bike? 3D printed shoes? If it can be 3D printed, this man can 3D print it!

[redgai]

Yep print orientation is important for layer adhesion and a more solid singular piece but you need to account for stress and shear force. I don't know enough about them but fillets, chamfer, and brace help transfer that force. Next time when you have sharp corners and your printed part have to deal with force acting on it, think about adding fillet and chamfer features

[brooklyn]

I'd like to see a video where you edit and redo the cup holder until it works correctly.

[OldCurmudgeonDP]

Another issue is the center of gravity of the cup being above or too close to the pivot axis.
Looks like insufficient layer adhesion and/or too little material overall was the main cause of failure.

[fernandofasanella]

In order to this to work, the center of mass should be lower than the hinges. Of course this in regard of orientation problems. nothing to do with the delamination. you should try a small coffee to keep it upright.

[MrGerhardGrobler]

Print orientation is of topmost priority when printing functional parts. Also walls/perimeters.
I default to 10 walls on my functional prints. And 50% infill.
Yes, it uses a LOT of filament. But it was made to last years.
Also. The cup holder was more than a bit top heavy at the start.
Nice bike.
I could buy a decent 1nd hand car for that money here in South Africa.

[MakerDIY]

Great video Joel! Love seeing practical print videos, even if they don’t always work out. Would love to see a follow up video where you try again though by modifying the model!

PS- Sorry about the trolls in the chat. I’ll leave it at that. Appreciate your positivity. It inspires me! 👍

[rickseiden]

When my father in law started having problems with fine motor control I bought him a mug like this and it really helped him.

[mtktm]

Lol I made one of these when I still had my jeep, out of coat hanger wires and solder, back in like 2003.
Fun times.

[goodBEan]

@3:37 weak infill with few walls: thats why it broke. If you are gonna put a strain on a part you have to make it more solid. Go at least 5 walls with 65% infill.

[MisterGlassy]

This cup holder has a major design flaw. It loosely supports the cup from the bottom. That's simply the wrong spot to hold the cup, here is the fix: Firstly, the cup is top heavy and wants to flip over because the center of gravity is above the gyroscopic mechanism. Secondly, because it's so loose in the cupholder it's allowed to jump about inside the cup holder. This design would do far better if it held the cup close to the mouth. That would move the center of gravity under the gyroscopic tilting mechanism, and it wouldn't be able to bounce around. Reduce the scale of the print until it's small enough to grasp the mouth of the coffee or print ring inserts to reduce the size of the holder. Get rid of that stupid hanging bottom all together. Lastly, change your fill to make it stronger. I would suggest using the adaptive fill options to add additional infill into the mount and the outer most ring. That part needs to absorb a lot of impact because it cantilevers out from the bike. You could also add some additional infill near the screw holes, but I think that's unnecessary.

[Loqcust]

Honestly Joel, this has inspired me to buy a new bike! I miss cycling places.

[ericsutton]

Add a spot to hold a small fishing weight to the bottom and it should steady the cup in an upright position. Of course, then you would need to reinforce a bit more overall.
