N Scale GP11 Paducah Geep

GP11 N ScaleAn N scale GP11 is now available. There are two versions depending on if someone wants printed handrails or do it yourself brass handrails.

For the printed handrails you can just download the handrails file here: gp11handrails – STL. The file is a .STL file and is in a zip folder. So you need to remove it from that folder on your computer before you try uploading it to Shapeways. Then upload it to your own Shapeways account (choose “inches” when asked). When ordering, select “print anyway” and Shapeways will print these for you. These are too delicate to put up for sale but Shapeways will print them for individuals. Contains two of each handrail piece in case one breaks, but they held up fine in my own test orders. Print in either Frosted Detail or Frosted Extreme Detail.

I was thinking of doing some other Paducah Geep, but I don’t know. There is a place that currently sells resin cast chop nose GP7 and GP9 shells

Frosted Extreme Detail Coming to Shapeways Soon

FUD Left FXD Right

FUD Left FXD Right

I’ll post more details as they become available. This will likely mean smoother, stronger models.

From Shapeways:

What’s happening? On April 15th we are:

Introducing Frosted Extreme Detail (FXD), with a higher resolution than Frosted Ultra Detail (FUD)
Retiring Frosted Detail (FD); FUD will remain unchanged
Renaming the Detail Plastics materials Acrylic Plastics

What does this mean for you?
If you would like to order your designs in FD, please do so by April 14th to ensure your FD order goes through, as the transition will happen on April 15th. As noted on our Material Status page, we have added 4 days to our expected production time for FD in anticipation of high demand.

Designs that you’ve printed in FD will not go away, and can be ordered in either FUD or FXD. We are updating success rate metrics so successful FD prints from the past will count towards FUD and FXD.

If you have a Shapeways Shop, customers will no longer be able to order your designs in FD after the transition. Products previously available only in FD will no longer be for sale unless you enable another material like FUD or FXD (when it becomes available.) If you have multiple products, the Pricing CSV Wizard makes it easy to update materials and pricing in bulk.

Why are we doing this?
Frosted Extreme Detail has a higher resolution than Frosted Ultra Detail, decreasing the layer height from 29 to 16 microns (the shorter the layer, the higher the resolution). While more expensive to produce, thinner layers means unprecedented detail and surface finish, sharper edges, less stepping, and stronger models. It’s perfect for the most demanding miniatures, figurines, and molds and masters for casting.

M-5 Caboose N Scale Now Available

m5 n

The M-5 Caboose is now available in N Scale from Shapeways.

The M-5 Caboose was used by ACL, SCL, Family Lines, and Seaboard System between 1964 into the 1990s. There were 438 total M5’s built.

This kit requires trucks, couplers, etched roof walk, paint, decals, and wire for grab irons (a small jig is included for bending grab irons). The picture above is of a pre-production model I put together (it isn’t quite finished in the above photo, but it’s close enough for now). I improved a few minor things on the model that is now available at Shapeways relative to the model in the above picture. If you want to model the Atlantic Coast Line, you can just use Microscale ACL decals. For SCL and Family Lines, here is a print ready PDF to make your own decals m5decals. I just print my decals with a laser printer on decal paper from MicroMark. After printing, seal the decals with a dull coat and they are ready to go.

N Bluford Shops Transfer Caboose Replacement Roof

Bluford Transfer Caboose

This is a roof designed to replace the smooth roof found on Bluford Shops N scale transfer cabooses. The Bluford Shops N scale transfer cabooses are great, but the roof (and some of the handrails) are not true to different railroads. This replacement roof is the kind of roof used on L&N Family Lines (CSX) bay window transfer cabooses. The roof on the Bluford Shops models snaps off with minimal effort and can be easily replaced with this roof. As always, soak the 3d print in Bestine. Also, for additional cleaning on non-delicate parts (like this roof) use a simple toothbrush and tooth paste. If anyone wants this roof in HO, contact me and be ready to provide me with measurements (in mm) of the HO Bluford Shops transfer caboose roof.

N Scale Pontoon Boat

N pontoon

Now available on Shapeways: N scale Pontoon Boat
It comes in two variations, one with railing detail and one without. The railing on the one without railing detail can be modeled graphically by printing out the railing as artwork and attaching it to the model.

Download printable graphics here (includes railing in four colors and floor carpeting in two shades of gray).

Shapeways Design Rule Definitions

Since the Shapeways site still doesn’t define in detail terms like “Supported Wire,” I thought I’d post some definitions they gave to me upon request. This should help other designers frustrated by rejected designs.

====
Detail vs Wall
Features protruding from a surface may be less than the minimum thickness for wall/wires provided they are not more than twice as tall as they are thick. 2:1 Height:Thickness. i.e a 0.32mm thick feature is allowed, provided it is not taller than 0.64mm tall

Free Wall
connected on one side to another part while free on the other side

Free Wire
Wire connected on one side to another part while free on the other side

Supported Wall
connected on both ends and retrieving structural strength from both connections

Supported Wire
Wire connected on both ends and retrieving structural strength from both connections must be less than 60:1 Length:thickness

Supporting Wire
A free wire supporting which is on the free end connected to an other part from which the wire does not gain strength

Wire vs Wall
A feature with a rectangular cross section will be considered a wall provided the long axis is 5 times the shorter axis. i.e. a 0.7mm thick feature will be a wall if it is at least 3.5mm wide.
