Roman Ballista

thingiverse

This is my modification of the Roman Ballista, and I've made some notable changes. 1. The trigger now extends fully downwards. 2. I've modified the projectile to accommodate bamboo sticks for a unique twist. 3. The original power lock kept breaking its pegs, so I replaced it with a metal peg. To tighten the string, I inserted small pegs into each area and used a wrench to secure them in place. Once they were tightened to my liking, I removed the smaller pegs. To assemble the new power locks, I utilized low-tack tape to hold everything together while I tightened the small pegs with the wrench. You can find the necessary pegs on Amazon at this link: https://www.amazon.com/gp/product/B07HLGVF8T I've used two different types of 3D printer filament for this project. The black components are made from HATCHBOX Sparkle PLA, which boasts dimensional accuracy within +/- 0.03 mm and comes in a 1 kg spool with a diameter of 1.75 mm. The copper parts were printed using Silk Copper 3D Printer Filament PLA, also with a diameter of 1.75 mm and weighing 1 KG (2.2 LBS). This filament has a shiny, silky appearance reminiscent of real copper.
