flowing pads for EUC, power pads, electric unicycle pads

these pads allow you all the customization you want. custom infill allows for custom stiffness. The default project is a good medium between comfort, stiffness, and ability to jump. If you wanted maximum comfort, you could remove all the custom infill and just have squishy pads. if you want to be able to remember where they stay on your wheel, simply cutout a small triangle from the flat base of each pad, and leave it on your wheel when you remove them.

uploaded are the stl's and project for prusa slicer which has all the custom infill geometry that is recommended for the correct rigidity.

YOU MUST USE CUSTOM INFILL FOR THE BEST RESULTS.
see pictures. I use internal ribs in the form of denser support structures inside the part. You can tweak and customize this however you want to get the pads as stiff or squishy in the areas you'd like. What I have is just recommended.

they are very large as is, i would recommend decreasing scale to 50-90% on x and y axis depending on wheel size. As is, they're really only suitable for the larger wheels (and printers)

Printer setup:
85a tpu
60c heated bed, warm enclosure also helps
250c nozzle
0.8mm nozzle
0.3mm layer height
3 perimeters
3-4 top layers
7-12 bottom layers
more perimeters or top/bottom layers will make it stiffer. I've found 3 perimeters is minimum for good strength and longevity
default 10% gyroid infill
custom infill geometry 25% gyroid infill or more for more stiffness. On the foot peg, some geometry has 35% infill. see project file for more details.
set volumetric flow rate to 4.5mm^3/s (or whatever your printer is capable of) to limit speed
custom infill geometry (see pictures)

make sure filament is dry

I print them at 80% scale only on x and y, leaving z axis at 100%
files are for Front and Back, should probably print each pad piece individually if your bed isn't large enough
