This is how many OpenR/C Truggy tires you get from one roll of Ninjaflex 3dprinting filament.
3dprinted with 4 perimeters and 10% infill.
So… five?
As much as i love your OpenRC work and printing things, i do need to question whether or not tires are worth using filament for. After all, you can buy a set of competition tires for under 20€, and a roll of Ninjaflex costs at least twice as much.
So do the 5 tires have a mass of 0.5kg? My off the shelf tires with foam and rims are only 85g each.
Looks like six to me, but yeah. Dissapointingly low.
@Thomas_Sanladerer For me this project started as a way to show of 3printing and with that in mind i´d say it´s definitely worth every penny. 
If you want really good tires you should buy them for sure. Don´t forget that this is just a proof of concept, an experiment & nothing else.
These 3dprinted tires are more expensive, will wear out faster, are heavier and doesn´t provide the grip that stock ones does. Actually they are no way near something you can get of the shelf. BUT they´ve got one thing going for them and that is that they are 3dprinted and that just blows my mind and makes up for all of the above. Because of that reason alone i think these are the most awesome tires i have ever had the pleasure of driving! =)
And yes, you get 6 tires from a roll.
@Wylie_Hilliard As a way to make printing easier i did them “solid” so they have a 4 layer perimiter and 10% infill.
im trying out some InnoFlex on my Replicator2X.
Do you have the stl or stp files for those tieres, i cant find them somehow. or are they not public (yet) ?!
ahh, thnx, i was blind, was looking at github only
many thnx. just started a printjob, curious how it will turn out
are you printing them with support and raft ?!
No support, no raft!
mhm, ok, strange, but when i look at a crossection of the stl-file then there is a part which will be printed in the air, or am i getting something wrong?!

on my Replicator2x it seems to be prudent to add one layer raft a little bigger than the tire. i simply placed a 120mm disc with the thickness of 0.2mm (when printing in 0.2mm slices). this way its sticks much better.
The raft from Makerware always comes off, to much tension when it cools down. With Innoflex i start with 65°C Platform and then let it cool down during print. Extruder is on 195°C. max extrusion speed i tried so far is 50mm/s for infill, 20 for the first layer and 30 for outlines
You need to download the STL from GrabCAD: https://grabcad.com/library/openrc-1-10-3d-printable-rc-truggy/files/Wheel/STL/OpenRC%20Truggy%20Tire.stl#
Check it out!
ärks, one wheel down the drain. i used the step-file and exported the stl from there 
@sicherlich_nicht sorry…
should have asked before. now the right stl is printig, takes about 8hrs
then ill try a Rim and see if its fits together.
an other stupid question
how the hell are you getting the tires on the rims? that was really hard work or is ninjaflex so much more flexible than the stuff from Inno3D?! dunno havnt got ninjaflex yet, but probably ill order some too.
anyways here a pic, Rim: silver ABS. Tires: black Innoflex:

Hey absolute agree it doesn’t easy to getting tires on the rime. So I redesigned the rims and split it in two parts. Easy to print better quality and more easy to getting the tires on 
let me know if you need stl’s
@sicherlich_nicht sorry about that so many projects, so many files. There is of course another version of the rims which is the one I use with printed tires. Thought I uploaded it but I guess not. I’ll take care of it tonight!
np, i managed somehow
had to trimm down those holders (dont know how to call them, which are supposed to keep the tires in place), to 1-2mm. lubricate the tires inside with some liquid soap, stick the rim in the tire (as far as possible), put the rim on the floor (not on a carpet) and a piece of wood on top of th tire (breadboard or something similar), and then step on it hard - snap - its in there forever 
@Daniel_Noree did you upload it already ?
what are you using primarily, grabcad, github or thingverse ?!
@sicherlich_nicht Sorry, i forget but it´s on GrabCAD now: https://grabcad.com/library/openrc-1-10-3d-printable-rc-truggy/folders/521647
GrabCAD is where i post the latest stuff.
