For raw 3D Printed kits:

  • Perfect for people on a budget or people wanting to assemble and paint it themselves.
  • Manual not included but can be made on demand. Stencils for logos included (if needed)
  • Printed on a high quality 3D Printer Ultimaker 2 with high quality FormFutura PLA with a standard resolution of 0.1mm (100 microns) or 0.15mm (150 microns) for really big parts to get the best result possible with a respectable time frame.
  • Parts are raw from the printer, meaning clean-up is required (removing support, brims) but don’t worry! I always design the parts with little to no support to ease up this process. Also, parts are designed to fit in one another for a good combination of ease of assembly, ease of post processing and overall strength.
  • Printed in silver or black, depending on what I have at the moment. Can be printed in custom colors, this will change the deadline and a small fee may be added (to be discussed in PM for more info)
  • 3D Printed items can be glued with super glue (cyanoacrylate) or epoxy. Depending on the model, pegs are included for easy and accurate assembly.

For fully finished props:

  • This props is perfect for cosplayers and/or collectors who want a prop, ready to go out of the box. Sold fully painted and assembled. Some props (rifles and sniper props mainly) may be sent in two parts for you to glue to avoid troubles during shipping. In that case, A small tube of hardglue will be provided.
  • The replica is made of durable PLA, some parts may be made of ABS, Nylon or other specific material depending on the filament I have at the time and properties needed.
  • It’s painted with an Iwata airbrush and Createx/Vallejo acrylic paint. Coats of varnish are applied to maximize paint protection.
  • Custom paintjob and other personalization requests can be made on demand.

This is not the droid prop you’re looking for? I take commissions so be sure to send me a PM about your project. (Although availability is not always guaranteed as I’m a one man crew with a limited schedule)
