Tesla Model Y cup holder adapter for large water bottles
A sleeve that drops into one of the Tesla Model Y or Model 3 console cup holders, which are about 75 mm across and 70 mm deep, and widens the opening to 90 mm so a 32 oz Hydro Flask, Stanley Quencher base or 1 litre Nalgene sits without tipping. The lower body is a 74 mm plug 60 mm deep with four 1 mm compliant fins that press against the cup wall, the upper cup flares to a 92 mm inner bore 60 mm tall with a 2 mm cushion rim, and three drain slots keep condensation out of the console. Walls are 2 mm; print it upright in PETG or TPU for grip.
Bottles differ by a few millimetres and cup holders differ by model year, which is why downloaded adapters rattle. In SpeakCAD you give both diameters, preview the sleeve in the browser without paying, add a phone-free coin pocket in the chat, and download the STL.
Design a cup holder adapter with a lower plug 74 mm outer diameter and 60 mm tall with four 1 mm compliant fins, an upper cup 92 mm inner diameter and 60 mm tall flaring over 10 mm, 2 mm walls, a 2 mm rounded rim and three 3 by 10 mm floor drain slots.
