They're done. And based roughly off the later SP cab forwards, seeing as I had no other prototypes in mind. I made variants with large and small counterweights, flanged blind, and with and without traction tire grooves. Haven't tested them in person, so I can't guarantee how well they work.

XL Boxpoks coming soon!

Oh! these are beautiful! Is the price per wheel? So if I needs 6 wheels, roughly $30+ for all 6?

Got my wheels in today. They look great. Just wish they had that polished appearance like actual bricks but not much can be done about that since they're being printed. Will post some pictures when I post pictures of my Cab Forward.

I've gotten mostly positive feedback and some helpful suggestions from the community since I started offering these wheels. Thanks, everyone!

I have had a couple requests for more types of wheels, and I finally got around to making some. First up, XL sized Boxpok drivers:

These are available flanged, with or without traction tire groove, blind, and all can be had with either a larger or smaller counterweight.

I have also made a size of wheel between large and XL:

These are available as spoked drivers right now, but there will probably be a Boxpok available soon. They also come flanged with or without traction tire groove, blind and with small or large counterweight.

I have not yet tested any of these, but I haven't changed any critical dimensions from previous wheels, so hopefully they work as well as the others. Everything can be found at my Shapeways store.

I've also added new colors and materials for all of my wheels. Shapeways now offers a premium black strong and flexible, which is about 2x the cost of regular. If anyone tries it, I'd love to hear how they work out. I'm also offering metallic plastic, which is an identical process to Benn Coifman's custom side rods, and the wheels should look the same as those rods.

Most of the colored plastic does not closely align with Lego colors unfortunately, but they might provide a better base if you intend to paint the wheels to match Lego. Cale has done this on his Blue Comet model recently, and the wheels seem to take paint well.

I just made an order from some of the Premium black. $140 for 12 wheels, yikes, hope it is worth it! Will probably get some of the XL Boxpok drivers if the premium black works out well. I love the large Boxpok drivers I bought for my SP Cab Forward, just wish the finish was a bit better but not much you can do with 3D printed stuff.

Just started putting together an order for some of these wheels! They are exactly what I've been looking for!

Might order them post Christmas, as they don't come cheap, and I've got presents for others to buy!

My shapeways order was supposed to arrive today. Sadly it did not, been having major problems with UPS and USPS lately... on another note, is it possible to get these made into .DAT files for MLCad etc.? Would be nice because then we can design for proper spacing which is quite difficult without buying a ton of each part.

These look great! Would love to use these at some point for a UK Bullied Pacific!

Got my shapeways order today! Somehow ended up with eight! additional wheels! Score! Here is a picture comparing the injection molded LEGO flanged/blind drivers to the "Black Premium Strong and Flexible" and to the "Black Strong and Flexible."

As you can see, it is definitely an improvement but still quite a ways off from the injection molded pieces. Wish Ben Fleskes could create some new drivers but injection molding is expensive...

Anyone heard from Nate in awhile? Hoping he will make the Scullin style drivers in the XL size. Only available in XXL right now.

Several members of my club have discussed the need/desire for larger and different sized train wheels, and the possibility of 3d printing them. Earlier this year, I was down with a back injury for a while, so I used the time to figure out some 3d design fundamentals and make my own. I don't have any 3d printing equipment so I put them on shapeways for my own use.

I have had a couple requests for these since word got out that I made them, so I set up a shapeways store:

www.shapeways.com/shops/shupp-s-brick-train-stuff

I have made XXL sized (the next size up from Ben Fleskes' XL sized), a size between medium and large, and a medium diameter train wheel i.e. not a steam driver, just a thin train wheel but with a larger diameter.

These are being offered at cost (I make no money) because I cannot guarantee the fit of the pin and axle holes and other aspects of the production which are out of my control, nor can I make any easy changes that would solve the problem.

I don't know if I will be making any more different designs, and I probably won't make any changes to the existing ones at this point, but feel free to suggest ideas anyway. Again, I'm not putting these out here for my profit, but just because I already had them myself, and I figured I should share them, and I don't have a ton of time to devote to it.

I have these notes in the store as well, but I will repost them here:

The ML sized wheels do not 'align' with other sizes of LEGO train wheels. If you have a standard small LEGO train wheel, a medium sized driver, a large, and XL and my XXL size drivers running on LEGO train track, the centers of each bigger sized wheel will be one LEGO plate higher off the track than the next smallest. As such ML drivers are not really 'in system' and may cause problems in some designs where multiple wheel sizes are used.

XXL sized wheels, while I think they are the right scale for many LEGO steam engine models, are a little too big for standard R40 LEGO curve track. If one were to use them in a flanged-blind-flanged arrangement to make, for example, a Pacific type locomotive, the two flanged wheels will be so far apart that they will bind in curves. The XXL wheels do work well when two flanged wheels are placed next to one another but, for other arrangements, you will need to look into after market wider radius curves if you are looking to run with these wheels. There are several options out there for wider radius curves, so maybe the curve issue is less important now than it once was.

Hey for my next Moc I wanted to test your XXL wheels, since I think they are the best size out there. But I´m tide on a budged and have to plan all my mocs on the computer.. Is there a posibilty to get LDraw Parts of the XXL Wheels???
