Marshall Blaster Pistol Instructions

Thanks for ordering the Marshall Blaster Pistol Kit.  Checkout our other Cosplay items here!


This item is a DIY kit and as such assembly is required. Painting is optional!


Please make sure you have everything before you start.

In addition to the parts above you will need glue. We recommend Loctite Super Glue


  1. Remove all support material, and trim any excess, bits from the parts.
  2. Each joint will need to fit flush. Some joints may have a little texture or may be slightly curled near the edges.
    • For the textured joints we recommend that you tape a piece of sandpaper to a table and sand the part by sliding it over the sandpaper. This makes for a nice flat edge. Use a sanding block on areas you cannot table sand.
    • On joints that are flat but the edges are curled up we recommend heating the part with a hair dryer or heatgun.  -----> (!!! CAUTION: If you get it too hot it will melt!!!!) Slightly heat the joint by quickly moving the dryer back and fourth over the area. You want to soften the plastic but not melt it. Once the joint is soft press the parts edge firmly to a flat surface, and hold until cool. This will make the joint flat, and allow the glue to adhere.

  3. Once the joints are all flush you are ready to assemble.  Put a little glue in each hole and on the mating surface of each joint.  Glue each part                 together as shown in the diagram and images below.



This blaster has a moving trigger. Lightly sand the tip of the trigger to allow it to fit all the way inside the body. The trigger is meant to be friction fit, but you may use a little glue to hold it in place if necessary.  Be careful not to get any glue on the moving part of the trigger or the body. 



    To get a nice finish you will need to take care of the print lines. After assembly you will need to coat the item with resin. This allows for smooth surfaces, adds a significant amount of strength to the item, and can even add a little weight.

    We recommend XTC-3D. It is a resin specifically formulated to coat 3D printed parts and it makes for easy sanding. One box is enough for many projects. XTC-3D is our go to when finishing any 3D printed item! 

    Other resins will work as well but make sure you are selecting a resin designed for your use case! 
    Coat the entire kit with resin, and be sure to catch any runs. Runs will make for more sanding later! You want a smooth even coat, with little or no impressions or protrusions. You may have to coat some areas more than once.
    You may skip areas of high detail and coat them with resin which has been thinned with isopropyl alcohol. This will preserve detail. 
    Be very careful in areas with moving parts so you do not glue the moving part into a fixed position.
    After the resin cures you are ready to sand and paint!
