This page has all CAD data useful in conjunction with Nummech's unmilled Shocker Slug bodies. These models use a separate page because the Shocker Slug bodies can't be classified as either SFT or NXT, due to the extensive internal redesign.
Two different types of Slug body models are available, representing both ends of the design spectrum:
· Unmilled blank models show the body in its initial 2x2 square shape. This can be used to create "cut" features that remove material from the outside.
· Tube models are a generic ultralite-style body that show the least amount of material required to make a functional Shocker. This can be used to create "additive" features outwards from the basic tube shape.
Both bodies can be used for checking a new design to ensure there are no interferences with any internals, and that the new design fits within the boundary of the 2x2 unmilled blank. Nobody says you need to stay within that 2x2 shape, but any additional feautres would need to be machined as separate components and somehow attached together afterward (this was done with the Smart Parts Strange SFT body ).
Check these pages for other models which may prove useful:
Shocker SFT files (all generic Shocker internals; SFT-only components)
Shocker NXT files (NXT-only components)
Feedneck files
Generic files
Barrel files (useful to create a wide view of the marker)
Shocker Slug unmilled blanks:
ACIS SAT file (.sat)
Description: Published model for a Nummech Shocker body blank in its unmilled state. This model represents the assembled body and transfer plate, which shows the shape of the marker body during the cosmetic milling process.
Note: this functional model includes milling for the eye cover features, which can be useful to proof your design and see where the eye covers are positioned. However, the "no eyes" model is recommended for use when developing cosmetics.

ACIS SAT file (.sat)
Initial graphics exchange specification (.iges)
STEP file (.step)
Description: Same unmilled body blank model as above, however the eye cover features have been removed. This is generally more useful when developing new cosmetics since the model is completely solid throughout the eye cover areas. This model is specifically intended to be used with Nummech's Slug-style unmilled eye covers which allow cosmetics to blend together.
I retained the original 2d sketch for the eye cover pocket, which might or might not translate when the file is imported. You can use the sketch for reference, or simply delete it.
Note: You must double-check your designs to ensure your new cosmetics aren't too deep. The eye cover area of the body needs to be wider than the rest, otherwise you'll come in contact with the eye cover screw head, NXT detent hole, etc. Use the "Tube model" body or the NXT unmilled eye covers to verify the design.
ACIS SAT file (.sat)
Description: Unmilled Slug-style eye cover for use with an unmilled body. This model can be useful to verify cosmetic designs. As mentioned, you should not create cosmetics that are so thin that they will interfere with the eyes or detents.
Shocker Slug Tube model:
ACIS SAT file (.sat)
Description: This body is functionally identical to the unmilled blank in terms of internals. The outside has been altered to show the minimum amount of material required to make a functional Shocker. This model can be used as a safety check, or the model can be used as a starting point to "add" cosmetic features outwards from the tube shapes.
Note: this functional model includes milling for the eye cover features, which can be useful to proof your design and see where the eye covers are positioned. However, the "no eyes" model is recommended for use when developing cosmetics.

STEP file (.step)
Description: Same Tube model as above, however the eye cover features have been removed. This is generally more useful when developing new cosmetics since this model has added material to surround the eye cover (and eyes/detents beneath). This model is specifically intended to be used with Nummech's Slug-style unmilled eye covers which allow cosmetics to blend together.
I retained the original 2d sketch for the eye cover pocket, which might or might not translate when the file is imported. You can use the sketch for reference, or simply delete it.
Note: You must double-check your designs to ensure your new cosmetics aren't too deep. Do not create any cuts into the eye cover section, otherwise you'll come in contact with the eye cover screw head, NXT detent hole, etc.
Manufacturing:
ACIS SAT file (.sat)
Description: This file shows one possible sample body workholding fixture which can be used to mill cosmetics onto a Slug body. This fixture can be used to position the body in order to access the right side, left side, and top side. This is absolutely the most simple fixture you could use on any type of milling machine. The fixture also has room to accommodate most vertical adapters and/or any future vertical adapters that may become available someday.
The fixture uses the following hardware: 2qty 10-32 x 1" socket head cap screws; 2qty 3/16" x 3/4" dowel pins.
Note: this fixture is not meant for use with a Smart Parts OEM Shocker body. The pinholes are not in the correct location.
PDF file (.pdf)
Description: These drawings are meant to accompany a Slug body to be of use for any machinist looking to design a fixture or otherwise perform work on the unmilled body. The drawings show details on how the bodies were made, areas that can be used for accurate measurements, along with areas that are not accurate. The reference sheets show drawings depicting the sample milling fixture (also available for download).
Eye cover cosmetics:
The above pictures highlight two possible situations when dealing with the milling around the eye covers. It's not necessary to mill eye covers at the same time as the body itself, but if you want the eye covers to match then they do indeed need to be milled at once. However, the eye covers can only be milled to match if the cosmetic cuts don't interfere with the eyes or detents. In other words, cosmetics that cross too deep into the marker body cannot be used with matching eye covers.Deep cosmetic cuts can still be used (within reason), but the eye covers cannot be made to match. The end result would be similar to a private label Shocker SFT, which doesn't use matching eye covers.
Use the "Tube model" to evaluate your design and determine whether the cosmetics will cross into the eye covers.
