- Thread starter pkfab1
- Start date
This is all I could find in my searches:
www.ultracustomfab.com
FRD-6 transmission | Ultra Custom Fabrication
Sixth scale transmission for SCX6 and custom applications.comes with adapter bolt to stock SCX6 skid.Gears are Mod1 reccomended driveshafts are LCX hardedned steel shafts

new and of course already out of stock... need more pics --- how does the motor mount? What size pinion range can it take etc?
Clean looking that's for sure - Vitavon style pricey almost

So at $275 a pop and already sold out it sounds like you should be firing up your printer and raking the dough, no?
I don't mean to be offensive I'm all for do it yourself --- but unless you have a HIGH HIGH $$ sintered metal printer your gearcase will be likely to fail being that thin and printed out of plastic trying to take on the pressures and forces that a MOD 1 gear case can out put considering the motor sizes and power outputs moving thru SCX6's....
I am just a novice johnny come lately so take my comments with a grain of thin air, but for me at least it would not be that "simple" to re-create this gear-case. If it was why are people shelling out $275 for it? Or maybe only a couple were sold in the initial run and its not actual that in demand?
To me, the forces these SCX6's are having to withstand are immense compared to 1/10 and 1/8th scale rig setups, plastic is not the best option pretty much anywhere in the drivetrain parts for it.
Or they have aluminum / steel metal 3D printers on the affordable list these days that I have no idea about? I'm sure its entirely possible, I don't really keep up that much anymore... but please by all means sign me up for 1 each!!!!

The only other high strength single speed trans that I know of for SCX6 out there right now is the Vitavon 1.5MOD gear at $420 not including the motor mount I don't, or maybe it does I can't remember. Are there others available?

No offense taken, you just didnt go to the same schoolI did. I don't 3d print for anything but a prototype. I went to school for industrial design, and would take it to my old shop and have a 7 axis cnc shit it out in aluminum or steel after the initial trial(s). Both 3d printers I have are now "old" by today's standards.
However, the Ender 3Pro will print a polymer filled nylon.
It could be "fashioned" similar to an old brat/frog transmission. 2 machined side plates for the flanged bearings and a 3d printed spacer to screw the 2 plates to on the outside. Make sense? The gears are flat! No sideways force. You can make the bearing pockets as big as you want on the sideplates. You just have to buy big bearings.
The 3d printed spacer, would essentially encapsulate the gears, and keep dirt out. Not much else of a purpose. Think of a clod gear case, minus the axle tubes, all in Mod1 and made smaller essentially
Maybe I need to get a SCX6

This is true, I certainly did not.
Personally, I rarely find it simple to go back to "old" places for things.... that could just be me though, guess I just don't like looking back anymore.
Once its old and gone, I'm not going back.
Where I live, school is expensive and rarely simple. Maybe you could use the school's resources, but ultimately the school won't print the item.
Printers I googled anywhere from $1500 to $5000 and they are not even saying they print in metal. Granted I don't know the first thing about 3d printer pricing other than last I knew printing in metal was one of the more difficult and pricey type of printing.
I just don't see it as simple, even if the process is. Again, I'm sure its just me --- maybe it is simple for pkfab ---- ? Is that fab for fabulous, or maybe fabrication ??

We are almost done with a new transmission for our SCX-6. Single-speed worm gear design. Complete with motor, it's under 400 grams. Crawler stuff only in that it's a massive gear reduction. Now we can use a tiny outrunner motor on 4s. Just sorting out if we are going to have an internal lube wick or if grease will hold up. It's paired to a new tucked skid plate.
Prototyping has been done on a Formlabs 4L with Tough 2000 material. It's the same stuff we used for our SCX-6 servo lay-down mount on the front bumper. Down the road we will write the program for the mill and bang a few out of aluminum. The skid will remain as 3D printed material; slides better over rock.

I'm looking at upgrading my ender 3pro from 2019 for Creality K2 plus combo. I have the qidi xone but that o ly prints in 120² mm and I want to print 1/6 bodies the K2 prints 350³mm which is plenty!
Not sure what materials it all prints yet, but I'm not too concerned about it yet.
The sideplates can be "machined" , ie drilled with a drill press. Same with the bearing pockets. Just takes patience and some sharp drill bits, a punch and a marker/blue. Work your way up.
Take 2 pieces of aluminum and clamp them together to get all the holes to match up. Drill your perimeter holes on the outside of the gears for the case to hold it together.
You old? Im 45 and going to jr college right now. Its hard, but not impossible

Gula, I hadn't thought about making the transmission the way you thought of it and honestly it opened a whole new way to think about the 3d printer.
I've been resisting for a long time but actually ordered one this morning.
As for drilling the side plates, beside clamping them together you can also 3d print a drill jig to get the bearing center to center correct. Biggest problem I'd have is getting those spaced dead nuts. Even with center punches, etc on a drill press.

Center punch, ALWAYS ! and work your way up in drill bit size. By .5mm if needed!
Also, If you clamp your workpieces to the drill press surface, you will have very minimal play/unevenness between the two workpieces themselves
Stub drill bits are key, as well as a center drill bit. Those are great for little things like this.
