  1. What does it do? - The ziio™ is a 3D printed CEW (Conducted Electrical Weapon) defense product that can be used as both a stun gun and a similar way to a Taser®/Phazzer® to project darts (or other deterrents) carrying high voltage discharges to help subdue an aggressor at a distance. The high voltage pulses act on a persons muscles making them contract and relax uncontrollably. Keeping an aggressor at a distance makes the ziio™ a much more effective deterrent than a normal stun gun. It can also be used as a normal stun gun if required.
  2. How many volts does it output? - The voltage varies from pulse to pulse, but typically in an open circuit condition 65,000 volts.
  3. Is it as powerful as other CEW products on the market? - It is very close to the power output of the CEW products that United States police forces commonly are equipped with and carry. Also as it can be discharged for longer periods than police CEW's it can effectively have a higher disabling force against an aggressor. It is not a toy and packs a serious knock-down punch.
  4. What does a Police CEW cost? - Around $800-1200.
  5. Can I modify it to make it more powerful? - The electronics should not be modified in any way to alter them from stock.
  6. What kind of cartridges can be mounted on the ziio™? - It can can accept Taser® and Phazzer® cartridges that include electrically conductive darts, pepper balls, practice cartridges and others.
  7. Is this product dangerous? - It is no more dangerous than a commercially available stun gun. As with all products similar it should be used as a last resort if retreat or removal from a hazardous situation with a threatening individual is not possible.
  8. Which states allow ziio™ unrestricted and without a license? - Currently: AL,AK,AZ,AR,CA,CO,CT,DE,DC,FL,GA,ID,IN,KS,KY,LA,ME,MD,MA,MN,MO,MT,NE,NV,NH,NJ,NM,NC,ND,OH,OK,OR,PA,SC,SD,TN,TX,UT,VT,VA,WA,WV,WI,WY
  9. Which states have some restrictions or require a license? - Currently: IL,IA,MI,MS
  10. Do any cities have laws against owning ziio™? - Yes, Currently: Chicago, IL. Ocean City, MD, Ruston, WA
  11. Do any counties have laws against owning ziio™? - Yes, Baltimore County, MD
  12. How old do I have to be to operate this? - Consult your local laws on stun guns and Taser® type products.
  13. Why is it unique? - Two main reasons; one it is possible to build at lower cost than anything on the market, also more units can be printed and stored in various locations more economically. So you always have one at hand, at home, in your vehicle or on your person (restrictions may apply please consult your local laws) . Two it is designed with safety in mind and requires the FireKey™ inserted correctly. The FireKey™ is very quick to insert for arming; without it the ziio™ is inert.
  14. How long does it take to insert the FireKey™ to arm? - Typically around 1-3 seconds.
  15. Can the FireKey™ fall out once inserted? - although possible it is unlikely, it has to be rotated and pulled out. When inserted it is held in place via magnetic force.
  16. How big is the FireKey™? - About half the length of a Sharpie marker and about the same width; see the image at the top of this page.
  17. Should I allow children to play with this? - No, even with the ziio™ unarmed it should not be considered a toy. The safety features are only in place as extra safeguards. The ziio should be stored appropriately.
  18. Does the FireKey™ contain electronics? - No, it uses magnetic force for arming and can be attached to a keyring or clip for convenient storage.
  19. Is the FireKey coded to each ziio™? - No, the key is generic and any key will arm any unit.
  20. What is included if I purchase this file package? - The package includes everything you need to print and construct the ziio™. 3D print files and a 60 page very detailed user manual and build instructions. The build manual includes full details on each step required, list of material and vendors and technical drawings. Also tips on use and cautions. The ziio™ has been refined over many design cycles to create parts that will print reliably on FDM style printers and to allow a successfully built product.
  21. How difficult is this to build? - Not hard at all; if you've built a few lego sets and like making things you should have no problems finishing the build. The manual has every step in detail with color photos to help guide you.
  22. How much will this cost to build? - It depends if you purchase all the recommended parts or already have substitute parts available (drawings of stock parts are included in the instruction and build manual to help you find substitutes should you choose to). In addition to purchasing the instructions and print files a stun gun is required ($79), the various other pieces of hardware required add up to around $35. Note some items have a minimum purchase quantity greater than the number required to build 1 unit; so you may want to share parts with friends or family which will save you money. Price quoted here is parts to build a single unit irrespective of minimum parts quantity ordering. Price estimate does not include shipping feeds, batteries or Taser® cartridges.
  23. So what is the absolute minimum cost I could build this for roughly? - Around $140 including the purchased files and instructions.
  24. How long does it take to build, excluding print time? - An expert could build it in just over an hour and a half. A beginner around two to three hours.
  25. Is the unit waterproof? - No. Do not get the unit wet. It generates high voltage electricity and may behave unpredictably.
  26. What plastic do I print this in? - Polylactic acid (PLA) works very well; other plastics include Nylon or ABS. It may require printer tuning for good results in plastics other than PLA.
  27. Can I print this on soluble support material? - If your printer has dual nozzles and can print soluble material as a support yes it can be used for an easier print.
  28. How long does it take to print? - It depends on your printer speed and layer height, however a typical time is 18-24 hours per side of the main body (2x) and a few hours to print the smaller items out.
  29. What print layer resolution do I need to make this? - The main body prints well at 150 micron print layers, anything between 100 and 200 microns should work well. Finer layers give a smoother print but take more time.
  30. What color should I print it? - It is highly recommended to print in bright Yellow or similar color to make it very clear to law enforcement that is it not a firearm.
  31. How much does it weigh? - depends on infill %, but at 18% around 550 grams including batteries and cartridge.
  32. What range does it have? - it can vary according to what cartridge is mounted, a typical range cartridge has a 15 feet range. Other longer range cartridges are available such as 25 feet.
  33. How do I test it once I have built it? - instructions are included in the detailed build and user guide on test firing and practicing.
  34. What batteries does it take? - Six CR2 3 volt lithium batteries are used; for long shelf life. Batteries should be checked every 6 months and replaced if defective.
  35. How do I put batteries in it? - The grip base has 4 screws for removal; once removed the batteries can be slid into place. The base is then screwed into place with a philips head screwdriver.
  36. What size printer do I need? - the main body requires a print bed size of around 215mm by 210mm minimum (assuming printed flat against the bed which is recommended in the build manual).
  37. What tools do I need to make this? - Apart from a 3D printer, you'll need general tools such as allen wrench, screwdrivers, snips and a little silicone RTV. It also requires 11 wire connections to be soldered.
  38. Do I have to be very skilled in making electronics to fabricate this? - No, the solder connections are simple small wire to wire connections; there are no circuit board parts required to be soldered. 
  39. Why don't you sell all the parts as a kit? - Processing and packaging fees would have to be added for the various pieces making them more expensive for the end user. As the product was designed to be as low a price as possible allowing final builders to source their parts makes the fabrication to be as cost effective as possible. Depending on future demand and requests this decision will be re-visited.
  40. I really want to build one but I have no 3D printer; what should I do? - There are many online services that will print parts from supplied files. You can shop around for the best deal. In addition we are working with several online 3D printing vendors to leverage very competitive printing rates for this product for our customers. Once we have a deal in place it will be announced on this website with links to the preferred vendor.
  41. Are you going to produce more products in addition to this one? - We are working on several other novel and inexpensive defensive products in addition to this one.
  42. Does the design pack include a holster? - Currently it does not; however please let us know if you would like one. If there is enough customer interest we will consider designing and releasing one. It will be a free download for customers.
