Many inexpensive one, but takes a long time (week or two) to ship. I tried these and I like them. They have very small holes, though, so beware.
Qables - plastic basic splitter
Viablue - mostly larger splitters. Best for speaker cable and interconnects.

Eidolic E-SXTM Modular Titanium Splitter (ultra compact, carbon or metal inserts)
Eidolic’s flagship splitter is an all-new titanium creation with choice of central insert, allowing the choice of metal or fiber inlays. It features the lightweight 6AL-4V titanium alloy with high polish finish standard on Eidolic’s top line. While compatible with the bronze and aluminum rings as well as the carbon and silver fiber rings from the titanium 2.5/3.5/4.4 barrel, E-SXTM was designed to be paired with a dark-alloy-plated fine-machined aluminum ring miniaturized from the center insert of the Peerless 4-pin XLR. The top & bottom sections screw together to allow the center insert to be exchanged. With 3mm front holes and 7mm rear opening. Its dimensions align with the classic Eidolic SX-4 for a familiar feel with exotic style.
