"Safety Cover" for Chamberlain Remote Control Garage Door Opener - Improved - Two Versions

Some time ago I made a “safety cover” is for the model 953EV-P2 Chamberlain 3-button remote control for garage door openers(see photos). That cover clipped onto the remote to prevent accidentally pushing either of the two smaller buttons; the cover did work, but sometimes accidentally came off of the remote. To address that issue, I designed two new versions of the cover :

Version 1 (Remote06) : This version is made with TPU; it slips over the remote like a sleeve and holds quite firmly.

Version 2 (Remote07) : This version is also a “sleeve” design (printed in PETG), but is much thinner than the TPU version. The design includes a “corrugated” section which allows the sleeve to stretch a bit.

As with the previous design, if either of the two small buttons need to be pushed on purpose, there are two small holes in the cover so that a small object (like the end of key) can still be used to push the buttons. The cover can still be easily removed if necessary.

Of the two versions, I prefer the second version - it prints much faster than the TPU version, and the “corrugation” also provides some tactile feedback.

Print Instructions

You can print using the included 3mf or gcode files. If you do not print the TPU version, it is  recommended to use PETG for items that will be in a hot car.

Print on edge using 0.3mm layer height. Make sure the “notch” end is facing up (the notch allows clearance for the visor clip).

Redesigned in a “sleeve” style to prevent slipping off the remote.
