TubDock: Hot Tub Drink Tray & Cup Holder System

TubDock is a drink tray that rides on your hot tub's rim, and comes off in one lift when the cover goes on. A bracket screws to the tub cabinet once and stays there. Everything else snaps together without tools: the frame drops into the bracket, the tray snaps onto the frame, and the can holders snap onto the tray. Lift the whole thing off before you close the cover. The bracket sits below the acrylic lip, so the cover closes normally.

Features

- A 2-bay tray (166 mm) on a bracket that stays on the tub

- 1-can and 2-can holders, snapping into fixed bays on the water side

- A 2-bay tumbler holder for 3" tumblers like the big 40 oz insulated ones (yes, the one everybody seems to own), insulated can coolers and cans in a slim koozie

- Up to four cans on the 2-bay tray: the 2-can holder latches at both ends, so it can hang half off the end of the tray. A 2-can plus a 1-can makes three, two 2-cans make four. The tumbler holder hangs the same way, so two fit side by side.

- 66 mm pocket: fits standard 12, 16, 19.2 and 24 oz cans and 20 oz bottles. Slim cans fit with a little room to spare and still sit steady.

- Floor pitched toward the water, with drain holes and raised ribs, so nothing sits in a puddle

- The tray rests on the rim and carries the weight there. The frame only keeps it from rocking or sliding.

- Ten slide-in TPU pads protect the acrylic and stop the tray skating (recommended)

- Optional bracket shim for cabinets set further back

- Every part prints flat on the bed, without supports or brims

What you need

- PETG for all printed parts, plus a little TPU for the pads

- 8 x #8 stainless pan-head or truss-head screws (not flat-head), in a length that is safe for your cabinet wall: long enough to hold, short enough not to reach anything behind it. 6 go in adjustment slots, 2 lock the height

- A drill with a 3 mm (1/8") bit for pilot holes

Installing

- Safety first: switch the tub off at its breaker before you drill. Wiring and plumbing run inside the cabinet: be certain what is behind every hole, and keep clear of the equipment access panel.

- Snap the tray onto the frame, set it on the rim where it will live, and push the bracket up onto the frame's posts until both clicks engage. That sets the bracket's height for you.

- Hold it flat against the cabinet, level it, and mark the six slot centers.

- Drill pilots and fit the six screws snug. The slots give +/- 4 mm of height adjustment.

- When it sits right, tighten everything, then drill and drive the two lock screws through the round holes in the end wings.

- Screw into the cabinet and the framing behind it, never into the acrylic.

- Drilling the cabinet may affect your tub's warranty.

Using it

- Tray off: press the latch through the finger notch in the frame's top edge and lift.

- Can holder off: press its latches through the notches in the tray wall and lift.

- Whole unit off: lift by the tray. The frame comes up with it and the bracket stays on the tub.

- Before you load it: check the tray is clicked onto the frame and the holders are clicked onto the tray.

- Drink tray only: it is not a seat, a step or a handrail. Don't lean or sit on it.
