About this 3D model

Multi-part twisted rope catapult model (you're going to have to assemble a lot). Glue is not necessary, but it is highly recommended for pieces that should not move. To make it functional, you will need elastic bands, thread, and a piece of printer filament for some axles (winch brake). I add assembly diagram, and videos, both assembly and test firing. This piece was part of a kickstarter project; There you can find more information and (may) answers:https://www.kickstarter.com/projects/daniamengual/siege-equipment-stl-files If you need more siege machines, perhaps one of these links may interest you:Small Siege Equipment:https://www.myminifactory.com/object/3d-print-small-siege-equipment-321061Covered Battery Ram:https://www.myminifactory.com/object/3d-print-covered-battering-ram-321053Siege Tower:https://www.myminifactory.com/object/3d-print-siege-tower-321047Trebuchet:https://www.myminifactory.com/object/3d-print-trebuchet-functional-333271And if you need more specific help, don't hesitate to ask here, or through my discord channel (https://discord.gg/JvmK3AZh6V)
