About this 3D model

Hello everyone, This is my first model that I have made with the help of youtube videos and my husband, who got me into 3d printing. This idea came to me in and yes I was told its alittle more complex for a beginer project but after many hours and help ofcorse its not perfect however I am proud of it and hope someone else might enjoy it. This model is a candycane catapult with mini christmas present that you can launch at any target. I used a santa sleigh that I had and aimed to launch the presents inside. It worked perfectly however I dont know how I can upload a video on here. This is printed all on one plate and does require some assembly which you will need an rubber elastic band. I included some photos for the assembly and hope that you can understand them as i find it hard to explain it in words. Please forgive me. I would also like any feedback as i want to get better at this. Thank you
