This custom-designed buttpad is made specifically for the Type 81 rifle platform, offering an increased length of pull in the case you weren't malnourished as a child and had access to 3 square meals a day unlike the rifles intended demographic. Moreover, I found that the stock metal butt plate tends to slide around a lot when used in conjunction with a plate carrier, and as such the aggressive dimpling of this model helped secure the cheek weld. Designed with a snug, secure fit in mind, it adds functional padding without compromising the rifle's profile or usability. Ideal for range days or extended shooting sessions, this 3D-printable accessory enhances both comfort and control.

Features:

Tailored fit for the Type 81 full stock

Ergonomic design for improved shoulder support

Durable and printable in flexible or semi-flexible filament

Easy to install – no modifications to the rifle required

Print settings:

Print it thick—I used PETG with 5 walls and 50% infill. Don’t expect to be able to butt stroke a blue helmet with it unless you use more walls, higher infill, and a tougher filament like ASA or nylon. Print with supports as oriented to bear the dimpling texture. If your printer's supported surface suffers, sacrifice a few grams of support infill and flip it and print that way.

Keep in mind, Type 81 rifles can vary slightly, so you may need to slightly adjust the X/Y scale for a proper fit. For reference, my stock measures 85 mm at its widest and 107.4 mm in length, and the buttpad fits snugly via friction. If you're worried about it, I'd suggest printing a ~60g shell with minimal walls and infill to ensure fit.

If anyone has experience with TPU that is likely a good candidate filament for this print, I'd scale down 2% for a snug fit and use that.

Thanks kindly.
