3D model description

This is my Octagon MOD for this airsoft sniper rifle.
I used this geometric shape to solve the problem of changing the position of the parts during use. I guarantee you 100% that using this design you will have high performance and consistency as any other expensive airsoft replica.
You have the possibility to choose for what kind of inner barrel you want to print the parts (bridged - LAMBDA Smart 03 6.03 x 430mm or unbridged - Maple Leaf Crazy Jet 6.04 x 430mm). For both you have to use VSR type hop-up buckings.

Added TDC dial_2 with 18 clicks instead of 14

3D printing settings

Use Colorfabb PLA HP because is heat resistant. It may be a little tricky to print but not like ABS or PETG especially if you have an enclosure for your 3D printer. It's very important to use a raft and print the parts one at a time with 2mm wall thickness. The rest of the settings I left them exactly like those for normal PLA.
Also print with as mutch infill as possible (if you have the necessary patience and time) to obtain a better durability.
Avoid unnecessary s and print the parts in the position they are loaded in slicer.
