This is a pair of heavy cannons that are compatible with Project Quixote and other Questing Knights and mechs of similar size.
The Upper Arms are compatible with factory twist-lock shoulders.
Don't be scared of the heavy support around the cannons. They peel off after degreasing and hot water soak. Just make sure to do that before UV curing!
These are also incorporate in Project Quixote, my modular mech base chassis. Photos and renders of that body are in the pics.
These free files are released in support of Project Quixote, the base modular frame show in the pictures, sold separately here on CG Trader. https://www.cgtrader.com/3d-print-models/miniatures/sci-fi/project-quixote-28mm-presupported-dieselpunk-modular-mech-kit
Clean and supported files. Optimized for resin printers.
Enjoy! Best, JBR
