Motor mounts for SR trucks.

BTW I have a 3D printer so just the files will be sufficient

Lols. Sweet deal. These are press fit. But I also have a CNC version that’s smaller. This is just test / plan B if CNC is too expensive.
I made these on a SLA though. Not toleranced for FDM.

Guys I have uploaded the Surf Rod press fit motor mount files to thingiverse! Free to all!
These are meant to be CNC’ed. While I did make a printable version that is more just an experiment and you need a SLA printer as there is no tolerance between the mount and the trucks as it’s a “perfect” fit.
Press fit motor mount for Surf Rodz 200mm RKP trucks.
If you do end up making a printed one I suggest you put support bars on the motor plates to limit flexing and reduce load on the mounts.

This is what the CNC version looks like. The small dot on the back side is to show which way to assemble them. The dot goes on the side of the truck that has the axel grub screw. It has a slightly steeper angle than the other side so its easy to put on upside down.
Cross section print was used to confirm fitment angles.

I just got a good price on the CNC in 6061 if I order 10 sets. 20pc total. No surface finishing.
Just feeling out if anyone is interested in a set for $50 usd shipped registered mail from Hong Kong?
I don’t want to do a big group buy or make a bunch of money, just want to make it worth my time and reduce the financial risk to me. I would just need 5 other guys to make it worth it.
These only fit Surf Rodz RKP 200mm hangers. The hole pattern is designed to fit mark88 motor plates rear mounted. But I think we could do some with no holes so people could drill them by hand to match their application.

Hey @wolffoxx I got some more info on the range as I recently put my battery meter back in. I charge to 90% according to the meter, and finish my 5km commute at 70%. So I think a range of 20-25km is possible if you use 100% of the battery. To be safe I wouldn’t want to use more than 10-15km
On a 1p lipo pack I don’t think its safe to go below 3.6v as the cells are not as well matched as big brand 18560’s and each cell discharges at a slightly different rate. So if your only monitoring total pack voltage one cell could get too low without you knowing. Once lipo goes below 3.4v they drop off a cliff and you can end up at 2v very easily. If you had a 3p pack then the difference between cells would average out and could be run a bit lower.

Btw those meters are not very accurate, mine reads 40% when the cells are at 3.6v
So $50 gets me two press fit 6061 aluminum pieces? I’ll take a set if that’s the case
edit: may be in for 2 lol the 4wd dream
Yeah a left and right if you get it with motor plate holes. Without holes they are the same part. I should probably put up a dimensional drawing so people can see if it fits their application. On the weekend I will have time to mount the motor plates and take some pics.

Thanks for the info! I recently built a pack from 4 X 3s 8ah Zippies. I wired them as 2 X 6s, which I combine in series for 12s. I charge them on two separate balance chargers. I’ll probably try your conservative cutoffs. I’ll run mine with voltage alarms, as well. No BMS, yet. Yours and @namasaki’s lipo builds were what I studied the most.
If your runing individual voltage alarms on all 12 then it should be safe to down to 3.4v

Im sure they are, NOT accurate or linear. But if you want the voltages, I charge to 4.05 and end around 3.85v so I am not taking that much out. I am not sure how to convert that into a percentage though? 20% seems reasonable.

Is this a war guys? 
How many more sets do you need for these mounts to become a thing?
If we get to 5 sets it should be a go, I have not mentioned it anywhere except this thread so far with very little additional info. I will add some more info shortly. Been so busy at work, 
I think we can get 5 pretty easy.
I am also considering making a motor plate also as the price was good on the hanger mount. Then we would have a complete surf rodz motor mount. Its just I have not designed it yet.
More photos info soon…
