Hệ Dây Đai Súng Dạng Link Module - IDPA (Modular Link Gun Belt System)

This is a DAA Lynx inspired / MSSB derived link based shooting belt system tweaked for IDPA.. I really like the MSSB System but it is designed for double belt / USPSA / IPSC style competition. I made this IDPA version to fit within the IDPA rules with plenty of wiggle room, be optimized for my connector of choice (Tek Lok), and to be very simple to print at home.

Simplified tl;dr - It is a 1.5 inch stiff IDPA focused gun belt you can put together at home with your 3D printer, some metal pins from Amazon, and a $20 ratchet belt kit from BSPS. IDPA rules (as of 2026) say no bigger than 1.75 inches x 5/16 inches and this belt fits comfortably within those rules.  

--My links are not compatible with DAA Lynx links - the roll pin hole  is too small and they are not dimensionally the same. DAA Lynx = 8.56mm x 38.45mm x 39.71mm and they use a M3 sized pin. I don't have a DAA Lynx belt so I wasn't able to see if upsizing them and using a M3 pin would work (but I bet it will or be pretty close)--

--Stuff you need to make it--

* X M2x35MM roll pins / pins - I got mine from Amazon in a 50 pack for 8 dollars USD in Jan 2026. Excel brand but any of them should work. - LINK
1 x DAA Ratcheting Belt Kit - I got mine here - LINK but you can find them on a bunch of other websites too. 
1 x 1/16th punch or similar sized tool - punch pins in / punch pins out.

--How many links do you need?--

Best thing to do is just measure your current belt and figure out exactly where it overlaps when it's at your desired tension. Convert that length to MM and then add divide by 36.53. This will give you your base count. You need to be aware of pitch as the CAD dimensions vs actual dimensions are different.

As an example: I wear a 36 in some pants and a 38 in others. I ended up measuring the need for 28ish + 2 ratchet ends but in reality needed 32 + 2 ratchet ends. I printed in batches of 6 and have some left over if any of my current links break. The discrepency of my count was due to pitch on the belt once the links started to curl around my hips. 

--Putting it together--

0. One side of the 3 prong end is reduced. That is the bottom. You can put a 1/16th inch punch in there if you need to pop the pin out for whatever reason. 
1. Put the links together reduced side facing down. Insert the pin and hammer away until flush with the top of the links. 
2. Using a 1/16th inch punch, lightly tap until fully seated against the reduced end. 
3. Repeat until your belt is put together how you like. 

**--Be aware of shrink. On my printer, the orange links came out quite a bit tighter than black did so I ended up having to convince them into the hole. Print some test links beforehand and run a pin through them. Do not clean them up with a drill :) --

To remove pins, stick the punch in the bottom reduced size end and punch up. It will be a tight fit or too small depending on your printer tolerances but it's over-reduced on purpose so don't be afraid to hollow it out a little bit. 

--Printing it--

Dev = 5 x 5 x 5 walls, 40% infill, 0.12 layer height / Black & Orange ESUN PLA+ and it was plenty strong but I didn't like how light the belt felt.
Prod -  100% infill / 0.12 layer height / Black & Orange ESUN PLA+ and it felt like the right weight to me.
