Dual Torch Goodman Handle for Orcatorch D710 + D520

A Goodman handle for the back of the right hand that carries two torches at once: an Orcatorch D710 on the thumb side and a D520 next to it, both pointing forward in parallel. The hand stays free for the inflator, the reel or a camera.

• Two snap-on clips per torch, with the jaw profile of my Orcatorch Torch Holders: 225° wrap, bore = torch Ø − 0.22 mm (D710 Ø27.0, D520 Ø23.9)

• The clips are separate parts: they slide onto dovetail rails along the handle and click into a window every 5 mm, so you can move them to fit your torch. Clips and their spring tongues print flat, so they flex in the layer plane and don't split

• Bolt snap clips at the rear end: each torch has its bolt snap tied short to the tail, and the clip holds the bolt snap's stem (Ø8.4 mm, 240° wrap, made for the XDEEP NX Small 80 mm), so nothing dangles

• Removable rigid hand strap across the palm: it slides into the body on dovetails and locks with two side levers. To take it off, spread both levers and slide it back. The included strap is 24 cm around the inside, sized for my hand: it fits bare (22 cm around) and in my 3 mm neoprene diving glove (see photo)

• Two Ø7 mm holes with chamfered edges at the rear corners, for a bungee loop around the wrist

• Raised D710 / D520 labels in a second color

• Body 106.7 × 127.6 × 16 mm, strap 114.5 × 47.5 × 25 mm; body shell 5.04 mm, strap 4.20 mm, clip jaws 4.20 mm: multiples of the 0.42 mm line width

• All 8 parts on one plate, 2 colors (black + green labels): the body prints the way it sits on the hand, with tree supports under the hand arch; strap and clips need no supports. About 8 h 20 min and 92 g (incl. 19 g of supports) on a P2S at 0.16 mm

• Print-tested in PETG: printed, assembled and fitted with both torches (see photos). Not dive-tested yet

Update (v7, November 2026): the hand strap sits tighter in the body. On v6 it wobbled slightly in its dovetail slots, so the strap's dovetail keys are now 0.15 mm wider on each side (picked with printed test keys in the body slot) and the teeth of the two side levers are 0.1 mm larger. Tested: the v7 strap fits snugly in my printed body. Only the hand strap changed: if you printed v6, reprint just the strap. The photos show v6, which looks the same.
