Please keep all these small parts away from children and pets, some parts have pointy ends, and they could be a choking hazard too.  Make or use these models at your own risk.

Update - 2/20/2026:    If you care about the future of 3D printing…

Please inform yourself about the legislation which is currently being considered in Washington, California, New York and Colorado, and will restrict and regulate 3D printers, and 3D printing software.  These bills may seem well intentioned, but they will lead to a government veto on what we can print, which software we can use, and how we can sell or transfer our 3D printers.  Criminalizing possible uses of 3D printers, and treating 3D printing hobbyists as though we need to be closely monitored, is contrary to the opensource and creative ethos which has lead to rapid innovation, and new small business or educational opportunities in this space.  These bills are very misinformed about the risks and rewards of 3D printing, and about the 3D printing community itself.  If they become law, they will have an outsized effect on 3D printing, create barriers to how we use and transfer our printers, and will hamper the hobby we love, as other states will very likely take up similar laws.

Now back to the model info:

There is a NEW version 2.1 of this Dummy 13 Weapons Pack, which has all the weapons here, as well as a new pump action shotgun, a watch, and several fully redesigned and updated items.  You can find that model here:

[https://makerworld.com/en/models/888476#profileId-844361](https://makerworld.com/en/models/888476#profileId-844361)

If you find these for sale on Amazon , Etsy or anywhere else, they are not being sold with my permission. There are no "authorized" sellers of these models. They were made for the 3D printing community, not for Amazon or Etsy sellers to profit from.

This is version 2.0 of the Dummy 13 Weapons Pack. It includes some updated models from version 1.0, and some new models as well. The shotgun was dropped in exchange for an MP5SD looking weapon. Also new, are a pair of MP5K's, so Dummy 13 can look like Neo taking on the Matrix, at least until the thought that maybe Dummy 13 is part of the Matrix enlightens a synapse in it's AI enabled cortex, leading to an existential crisis…

Once you've rebooted Dummy 13, it can be outfitted with a pair of AI friendly All-American survival knives (red bandana encouraged, but not included). If Dummy 13 needs more pew-pew, and less stabby-stabby, the v1.0 handgun models are still included, with a slightly updated design that will hopefully keep them more secure in the holsters. The remixed holsters from Mici's original design are also still included for convenience, as are the remixed katanas, with a slightly different handle and tsuba (guard) design. The handguns and holsters go great with Mici's Dummy 13 Deadpool costume, in case you may be wondering.

I almost forgot to mention, the MP5SD looking weapon has an extendable stock*

*The stock will only extend if the printer is really dialed in, otherwise it may end up fused. It took about a dozen test prints to get the telescoping stock working right, and my printer is pretty decently dialed in (cough - just ignore the stringing in the pics though :D). If it does seem a bit stuck, sometimes giving the stock a light twist back and forth can free it. But if it won't pop in or pull out with a modest bit of effort, it's fused, so enjoy your MP5SD looking static model, and forget I mentioned anything about an extendable stock.

There is an integrated support for the rifle in both versions of the STL's, and it's based on a 0.2mm layer height.  You may notice a warning in the slicer about “floating regions”.  That warning is due to the integrated supports with this model, and can be ignored.

The files here include a card kit, and a non-card kit version of the STL.

A few notes about adhesion:

I recommend trying the updated v2.1 model here, which has many fully redesigned parts, a couple new parts and a fully redesigned frame, which may help with the overall printing experience.  These models are however include small features, so the tips below should help to improve your prints of this model (and in general).

You can use a smooth or textured plate, however a textured plate which will help with adhesion. Due to the small features, promoting adhesion is important when printing this design. Some suggestions for promoting adhesion when printing this model are:

• Clean the build plate with dish soap (I use Dawn which seems to work very well for this).
• Textured PEI has generally better adhesion performance than any smooth plate, so try using a textured plate if you have issues.
• If you have an open frame printer (like the A1 or A1 mini), try to place your printer so it is not in a drafty area, or under or near an HVAC return, if possible. Temperature swings caused by drafts can case many issues, including adhesion problems.
• Use glue if your build plate supports it.
• You can also add a brim or paint on "brim (mouse) ears”, to assist with adhesion in the slicer.
• I was also told that adding tree supports can help if the butt stock of the large rifle has issues.

Changelog:

11-20-2024: If you've had issues printing the knives, and would like to help me test an update to this design which could help, please try the test model named “Weapons_Pack_v2-2Z_KNIFE_TEST_E.stl” (see pic below).  I've never had issues printing the knives on my printer, so although the dozen of tests I've run on the update have been fine, they do not prove much (so I could use feedback on the test design from somebody who has had problems with the knives).

2/24/2024: There is a minor update to the model, which adds some small details to the knives and katana handles. The knives are also redesigned to fix a problem with the original models.

12/17/2024:  There is an new version 2.1 of this model with some new weapons and others which are fully redesigned.  You can find the new model here:  [https://makerworld.com/en/models/888476#profileId-844361](https://makerworld.com/en/models/888476#profileId-844361)
