M4 carbine

thingiverse

This is the M4A1 carbine model, crafted with REC ABS and built to be printed in 8 separate pieces that snap together without requiring any glue. The fully assembled length measures an impressive 530 mm or approximately 20.8 inches from tip to tail. Here's a rundown of the recommended print settings: Rafts: Set to no, so the print starts directly on the bed for optimal first-layer adhesion. Supports: Enable supports where necessary to ensure stability during the printing process. Resolution: Aim for a minimum resolution of 0.2 mm for a high-quality finish and crisp details. Infill Density: Adjust the infill density to around 40% for a perfect balance between strength, weight, and print speed.
