Colt M16 model
thingiverse
This is a custom version of the impressive replica model created by Nap Bollemeijer. Please note that he converted this to metric and rounded it to 0.05mm, making it not suitable for producing a real firearm but perfect for creating a detailed plastic display model. I'm not sharing his original design, instead, I've modified it myself to create two separate parts that can be printed on a 5.5 inch SLA printer. One version allows you to orient the pieces yourself, while the other was pre-oriented in Netfabb using its calculations for minimal support requirements.
