I got sick of having my garage door remotes sitting in the cup holders, so designed these two clips that slide over the sunvisor.
There are two models - one is for thinner sunvisors (designed for with an older Mitsubishi Outlander/Nissan X-Trail), and one for thicker vehicles (later model Toyota Corollas). Designed for this sized remote: https://www.gomerlin.co.nz/product/premiumremote-security2-0-security/
I've provided the STEP file if you want to adjust to fit your own.
There is a hole at the bottom if you need to zip tie the remote in more securely.
Suggest print in ABS or ASA to avoid the interior heat of the vehicle making it droop and fall off.
Print on it's side to not use any supports (some small bridging required).
