Precision modular Rifle BIPOD (F-CLASS)

Hello everyone,

UPDATE 14.02.2025: Presenting update 1.2 and a new version of the bipod designed to be fully printable on the A1 MINI!!

Version 1.2 also introduces:

• improved latches for the main screw sleeve
• a slightly reduced size of main adjustment knob
• the main screw is now cut at the top and bottom for easier printing

!! A1 MINI version !!

This version is slightly smaller, but I managed to maintain a fairly wide height adjustment range of 16–24 cm measured from the bottom of the ARCA/Picatinny rail.

The ARCA and Picatinny heads are compatible with version 1.1.

 

UPDATE 26.12.2025: Introducing minor updates in version 1.1

Most of the new parts are compatible with version 1.0. For example, if you want to update the adapter mounting to the version 1.1 design, you only need to print the modified parts.

What changed in v1.1:

1. Minor design adjustments for an improved appearance, resulting from the new leg design.
    

2. In version 1.1, the feet now move on two axes to provide better contact with the surface. If you don’t like this feature, there is a separate profile with single-axis feet, similar to version 1.0. You can also continue using the feet from version 1.0 if you already have them.

3. The Picatinny/Arca mounting head is now attached to the bipod base with a screw. This ensures significantly better stability and eliminates any movement between the adapter head and the bipod.

4) The clip securing the main screw has been enlarged to make removal easier when folding the bipod. Simply remove the lock pin, unscrew and take out the main screw — the bipod can then be folded into a much more compact form 🙂

5) The layer height has been changed to 0.16 mm for improved print quality. If you prefer faster printing, you can switch to 0.20 mm — all parts should still fit properly.

Print profiles are in 100% infill, you can try smaller infill value but i suggest no less than 60%

Hope you’ll like all the improvements! Please let me know if you have any suggestions 🙂

UPDATE 23.09.2025: Added Picatinny adapter. Assembly is the same as for the ARCA rail, so follow the mounting directions in that manual.

Today I present a modular bipod for precision shooting (F-CLASS).

The bipod is entirely 3D-printed and it  comes with a head for mounting a rifle on an ARCA-SWISS rail or Picatinny RAIL

There are separate print profiles for bipod and mount.

The bipod has an adjustment range (measured from the bottom of the ARCA/Picatinny rail) of about 18–28 cm, with very fine adjustment by turning a screw.
The bipod also has a tilt lock that is engaged by tightening the central screw.
The feet are movable and can also be printed in TPU.
 

Intended more for small-caliber firearms or Airsoft (I don’t know how it will perform with larger calibers).

Check the attached photo instructions in the PDF for how to assemble both the bipod and the ARCA-SWISS head.
