Hold still dummy!

This stand stands above other dumm stands by holding your dummy secure while it takes on a precarious position.  Both arms are adjustable in 36° increments.  Once you find the perfect angle, tighten the bolt to lock it down.

Note: PETG is strongly recommended for the 200% and larger sizes.

🔧 Assembly Guide

BOLT → SMOOTH HOLE → THREADED HOLE
The smooth (non-threaded) hole is always sandwiched between the bolt head and the threaded hole.

Get an arm the wrong way round and the bolt screws into the near hole instead of the far one — the joint never pulls tight and the stand stays floppy.

Know your holes

Every Lower Arm has two different holes, one at each end. They look the same from the outside — look into the hole:

• Threaded hole — ridges spiralling down the wall. The bolt screws in here.
• Smooth hole — clean, straight wall. The bolt slides through; it does not grip.

The golden rule, at every joint

1. Bolt drops in from the outside.
2. Shaft passes freely through the smooth hole of the part you are adding.
3. Shaft screws into the threaded hole of the part already on the stand.
4. Tighten and the two parts clamp together — friction locks the joint at any angle. That's what makes it a locking stand.

Build order

1. Start with the Base. The threaded hole in the upright hub is your first anchor.
2. Add a Lower Arm. Put its smooth hole over the base hub. Drop a bolt through and screw it into the hub. Its threaded hole now faces outward.
3. Add the Upper Arm. Its smooth ring goes over the arm's threaded hole. Bolt through, screw in.
4. Clip on the Adapter. Press it into the claw — no bolt. The adapter is what connects to your Dummy 13 figure.

Make it taller

The Extensions plate prints spare Lower Arms. Each extra segment = 1 Lower Arm + 1 Bolt.

Same rule on every joint: the new arm's smooth hole goes over the previous part's threaded hole.

If a joint won't tighten

• Bolt spins forever / never gets tight → an arm is flipped. Undo, turn the arm over so the smooth hole faces the bolt.
• Bolt feels stiff immediately and won't seat → cross-threaded. Back it out, start it straight, let it catch gently.
• Stand droops under the figure → check every joint, then nip each bolt up finger-firm. Don't overtighten — 3D-printed threads will strip.

👉 Tighten finger-firm only. Firm is plenty — friction does the rest.
