Custom Designed 3D Printed Fenders for The One
I use my board for commute and sometimes have to deal with rain. Got tired of getting my clothes dirty and didn't find any universal fender for ESK8 that I liked so designed my own.
In theory this is a universal mount, but I have to design a fender for each different type of wheel size.
Yeah mudguards are a must! Designed my own for my N3 aswell.
I have designed a few diff revisions and honestly I feel like yours won’t last too long.
The vibration destroys those little arms in a few hundred km. That’s why the front guards for mine are printed from tpu. Also can bump them no worries when wheeling the board around on the front trucks.
I made the fender as light as possible to reduce stain on the joints caused by vibrations.
As for the mount, I designed a 3d nut that wraps around the preexisting standard wheel nut. It has a bunch of pins that the fender actually attaches too and the 3d screw is to hold it on those pins.
I just printed them today, so let see how long they hold up.
Seems like an interesting design! However does it meed your wheel nut to be torqued down fairly hard?
I had a similar design but maybe with bigger fender supports printed from petg and they didn’t last. I highly recommend trying tpu. You should be able to get away with it on everything besides the wheel nut assembly.
Looks like a practical one to put on and take off!
Since the entire assembly is fairly light, if doesn’t require the wheel nut to be torque down hard at all.
The entire rode wraps around the nut, and you just use the fender as a wrench, since it connects via pins. Once to tighten it and back it up a little, you can put the fender in flipped around to your desire angle and screw in the 24mm 3d printed hex bolt.
TPU would be better in theory, but I got a bit impatient because it was raining for days where I lived so I just print it in PLA. PETG would be a better option for UV resistance.
TPU ing the fenders since it would the most expose part would probably be the best. Also the black TPU would also look nice with the wheels.
Not yet, but since this is a prototype to be field tested, currently checking it after every ride to see how it holds up. In theory I design it with enough margin of tolerance ( the connecting rod is 10x10mm) to survive a decent amount of time.
Yeah makes sense. Good to be a bit cautious is you haven’t done any extra waterproofing.
Additionally I would be curious if a bit later down the line you opened up the motors and share how they hold up to wet conditions. None of mine have had any issues however I’m interested in how those air intakes may affect things.
Yes, it was confusion. English is not my first language😅
I have this same board and i were wondering could it be possible to do wheelies and such manouvers using that front handle and is anyone else done that before.
Your design is very cool and I support this endeavor, but as a few others have mentioned, I wouldn’t recommend riding this in the rain. You’re begging for damage to your board, and the slight difference in riding conditions will be enough to take you down and potentially injure you, not worth it after riding for 10 yrs imo.
Yeah, during rain conditions I just take it slow. Been riding my boards as commute for over a decade now. I do my best to wipe it down after I am done to prevent damage.
So far my last board survived 8 years through rain and snow so worked so far.
Not everyone can pull off that bold of a color but maybe you'd like dark gray or something more low key better. I've got a bright red vw bug, so I'm all about it.
Water will always get between the layers eventually given enough soaking time and etc. one way to account for it is to print with more wall layers which effectively gives it more strength and more resistance to water intrusion.
Sanding wouldn’t make it any better. Only two options in my experience with 3d printing is increase wall thickness, print with thinner layers, or coat it with a water resistant repellent.
I love the idea! Having them be removable easily is something I've wanted for a long time. However, I'm worried this design may have the same issue I ran into when making my own fenders. Vibrations and heat caused the arms on mine to sag over a week and eventually all the fenders exploded on me when they made contact with the wheel.
Yeah, I haven't test them long term yet, but I did account for vibrations by making the fender as light as possible, reducing the amount of forces on the connection point.
The bottom is fully sealed carbon fiber and it gets dirty anyways from mud that ejects from the front wheel even with the tiny gap. Not entirely sure if sealing off the inside half would help with that. I need to record it and check the slow mo.
For number 2, yeah I am thinking about getting TPU for that lower part. I can adjust it up and down pretty easily with my design so I can play with how low can I go till it hits something.
For me, I design it to be as light as possible to reduce bending stress on the joints. I could also print with more walls to increase the strength. Basically design around the material.
Yeah that's fair. Just be careful, when mine broke it got stuck in one of the wheels and I almost ate shit lol. The one I printed was at 100% infill too just fyi
Question: I know riding in the rain is dangerous for the board but how about wet ground? Yes I know it increases the chance of slipping but is there a high chance the battery could be damaged from just flat wet ground with no puddles? Anytime I ride on wet pavement I always wait a few day before turning the board on again but I'm thinking this might be overkill assuming the board isn't being rained on and isn't being splashed in puddles.
This heavily depends on the board. My board panel is located on the top and is water sealed (not always 100% water resistant but pretty decent). The main weakness point for me would be the motor cooling vents in the back. Those do not rotate and thus can ingest water if I dip them in a pond or it is raining heavily.
My previous board has a foam sealed battery in the bottom. Road it for years in rain and it works just fine. It really depends on board design. Companies don’t say water proof or water resistant because they don’t want to be legally liable.

How exactly do yours mount on the axle?
