Eartec UltraLITE Single Saddle - Backstage cart lip (one piece, strongest)

HOW IT MOUNTS
  BACKSTAGE CART LIP (ONE PIECE, STRONGEST)
    The cart-lip slot is printed into the holder, so it is one piece and as strong as it gets.
    Hold it tilted, hook the slot over the upright lip on the edge of a Magliner / Backstage-style cart
    shelf, and rock it down until it sits flat against the side.

    Notes for this holder: One piece with the Magliner/cart lip block (shipped part).

HOW IT WORKS
  A home on the cart for one Eartec headset, so it does not end up in a bin or on the floor, tangled or with the mic live.
  Fits: Eartec UltraLITE and UltraLITE HD single-ear headsets (ULSM / ULSR). The rounded-rectangle seat on one end takes the large temple pad and the round cradle on the other end takes the ear cup.
  How it holds

  - The band lies across a roof shaped like the inside of a headband, in a trough between an 8 mm back stop and a 5 mm front nub, so it cannot walk off toward or away from the cart.
  - Each ear pad nests in a cradle at the end of the part: a tall oval mouth with a 4 mm deep seat. The band's own spring presses the pads into the seats, so the cups cannot swing on a moving cart. The oval is tall, so the cradle works with the band at any length.
  - The top and front edges of each seat have a 45 deg lead-in, so lifting the headset up or pulling it toward you opens the band by itself. The back and bottom edges keep the full 4 mm, so bumps do not shake it out.
  - Mic boom: swing it UP before you hang the headset. Eartec booms auto-mute in the UP position, so a parked headset is silent on the channel. The boom pivots in the middle of the cup's outer face and stands straight up beside the part. Nothing on the holder touches it.
  - One hand: lower the headset straight down over the part. The pads ride down the trumpet sides and drop into the seats. To take it, lift it straight up.
  Check your headset (2 minutes with a ruler)
  1. Pad to pad: hang the headset on your hand and measure between the two ear-pad faces with the band at its shortest. It should be 110-125 mm (the saddle holds them 126 mm apart, so the band's own spring presses the pads into the cradles).
  2. Ear-pad diameter: 62 mm or a little smaller fits the 64 mm cradle.
  3. Crest to cup centre: from the inside top of the band to the middle of the ear pad, band shortest and longest. The cradle covers 95-125 mm.
  4. Cup depth: from the ear-pad face to the outermost point of the cup, including the boom pivot. Drawn at 44 mm; it sets how much free lip each end needs.
  5. Temple pad (single-ear only): its width front to back and its height. The seat is 60 x 64 mm (drawn for a 56 x 60 mm pad); a pad up to that size nests in it.
  Sizes are estimates. Eartec does not publish headset, ear-cup, band or boom sizes. This part is drawn from photos and the published weights, with generous tolerances. Before you print, measure your headset (see "Check your headset") and compare with the numbers here.
  Numbers

  - Sticks out 85 mm from the cart side (the part itself)
  - Hangs 162 mm below the deck; the block top stands 42 mm above it
  - Takes 126 mm of the lip; needs 45 mm of flat cart side below the lip for the back plate
  - A hung headset reaches about 86 mm out from the cart side (the cups)
  - The cups hang about 42 mm beyond both ends of the part, so leave about 48 mm of free lip at each end
  - 103 x 126 x 204 mm (out x along the cart x tall)

TEST THE FIT FIRST
  Carts, bars and tape rolls vary a little. Before a long print, print the small fit test from the
  Test pieces section of the site (or this part at low infill) and check it on your own gear.
