Regulator Holder with Swappable DIN / M26x2 Inserts

Hanger for drying and storing regulators: screw the first stage into a threaded socket and hang the whole set on a hook or rail. Up to three first stages on one holder.

What's new compared with the original:

• Three arms with swappable threaded inserts: each insert slides onto a dovetail rail and clicks in with a spring latch, so you can mix DIN and M26x2 as you need

• Inserts: DIN G5/8" (14 TPI) and M26x2 (EN 144-3 / nitrox); 17 mm deep socket with a solid floor

• Two loops on the body for the long hose's bolt snap, so the long hose hangs neatly instead of dragging on the floor

• Raised DIN / M26 labels in a second color

• 33.6 mm thick body, R3 rounded edges; loops lie flat on the bed, no supports needed

Update (v2, November 2026): the inserts are 3.5 mm taller, with a 17 mm deep socket instead of 13.5 mm. With v1 my DIN regulator screwed in easily but bottomed out before it was fully home. Tested: with v2 the depth is right. Only the inserts changed, the body is the same. In my v2 print the inserts are green with black labels; the photos still show my v1 inserts (black with green labels).

Files: 3MF with 2 plates (the body in one color; 3 x DIN + 1 x M26x2 insert in 2 colors), STL (body, DIN insert, M26x2 insert). Print the combination of inserts you need. On a P2S at 0.16 mm the body takes about 4 h 04 min and 67 g, the inserts plate about 4 h 35 min and 66 g with 38 filament changes (Bambu Studio estimate).

Print settings: Bambu Lab P2S, 0.4 mm nozzle, 0.16 mm High Quality, PETG, 2 walls, 15% gyroid. All wall thicknesses are multiples of the 0.42 mm line width; exact CAD (B-rep) surfaces with real fillets.

Note: the photos show my personal print with my name raised on the front. The files are clean, with no name, so you can add your own or leave it plain.
