Since MechWarrior Catapult 3D model has gained so much popularity on our marketplace, The 3D modeler came up with a surprise, designing 3 different MWO weapon kit to your regular MWO 3D design.

#1 Weapons add-on pack

This set brings you the opportunity to equip and upgrade your regular MechWarrior Catapult with right and left arm large laser guns, with right and left torso medium lasers. Equipping your MWO 3D model with these weapons you will upgrade it to CPLT-J model. 

#2 Weapons add-on pack

This set brings different types of laser MWO clan weapons that you can print and mount on your regular MWO 3D model. Upgrade the regular 3D model with powerful and hard-hitting laser guns that trigger the enemy and destroy throwing a rain of shots at it. The laser guns are very effective in producing damage and at keeping the enemy at distance. 

#3 Weapons add-on pack

Upgrade your regular MechWarrior Catapult model with awesome and direct fire weapons. Add a pair of PPc MWO guns that are capable to inflict all their damage at once. Mount medium lasers and machine guns and upgrade your 3D model to CPLT-K2 Mech model.

Every gun from the set is modeled in Maya 3D modeling program. The add-ons are available for download in STL files, zipped in a single folder. The files underwent review and correction in Netfabb. They are error-free and ready to be sent to print, using any 3D slicing software, such as Cura, Simplify3D.

These add-ons are the perfect upgrade solution for your already printed, regular MechWarrior Catapult 3D model.

Bring the BattleTech universe into the real life by printing and assembling realistically looking, upgraded models of the large bipedal combat vehicles.
Buy Mech Warrior Weapons Add-on Packs for printing by clicking on the green “Buy” button in the top-right corner of the page. Proceed to checkout, provide your PayPal or credit card details and download the files on your computer. Use your desktop 3D printer to print them and mount on your regular MechWarrior Catapult 3D model.


On 26.12.2016 the model files have been optimized and made solid. They now are adapted to be 3D printed using any slicing program. 3D model files are already available for purchase and download. 

This model was tested in Cura 15.06. To avoid printing problems, we recommend the following settings:


  • Layer height: 0.1mm*
  • Initial layer thickness: 0.3mm
  • Bottom/top pattern: lines
  • Skin perimeter line count: 0
  • Horizontal expansion: 0.04mm (when entering 0.04mm index, the 3D printer perceives the model as monolith, i.e. as having no hidden layers).

*Layer Height 0.1mm is recommended for a better quality for the printed model. However, the printing time will double.

Check this **Simplify3D User Guidelines to avoid any 3D printing problems with this software.
**On 26.12.2016, the 3D model files have been optimized. You can print them without following these Simplify3D guidelines, as the model is solid.

As a STL file provider, our goal is to ensure that the files are error-free and printable in the most accurate way. This is why, we only test print the most difficult segments of the model’s parts.

The model's parts have been tested and printed in PLA. In case you need advice where to get your filaments from, check our partner's website.
