For kaewon's Yippee Ki Yay: https://odysee.com/@kaewon:9/Yippee-Ki-Yay:6

Fixed MP5 stock converted into storage compartment with trap door butt pad, inspired by unseenkiller's A3 storage stock

Use two m3 or m4 hex nuts slotted into the inserts to secure the butt pad to the stock, choose the stock stl appropriate for your screw/nut size. vanilla yippee is m4
The butt pad can be printed flat or on a custom support tower for the best surface quality
If printing the pad in TPU, flat is your best bet but supported works too if you delete the tower and use slicer supports instead
You can print the trap door in TPU too, but it wont be very secure, you should probably print it out of a more rigid material instead

Slicer settings for the stock are up to you, probably should at least make sure you get solid walls until the storage compartment is printed
After that I would do 3-4 walls with strong but low density infill like gyroid or TPMS-D

!!! Turn off 'Reduce Infill Retraction' !!! absolutely not worth the risk of over-extrusions leading to nozzle strikes on such a long print
