ECU - A few part updates and details

Added 2025-11-07 23:18:00 +0000 UTC

This post contains a few minor part upgrades I used on my Ecto Containment Unit build. I hope other find them useful!

I continue to tweak and modify things about my ECU build so I thought I'd share a few part updates and details.

Door Magnet Mounts

Several have requested some more information on the magnets I used with the ECU door. It helps keep things closed. I used 8mm x 2mm circular refrigerator magnets. Two parts are included in the files here for holding them in place. Glue in your magnets, and then secure them to the ECU door and main case respectively. (Careful not to mess up the polarity!)

Lever Upgrade

The original part can be printed in one piece. After an incident broke my handle (an over-enthusiastic kid on Halloween gave mine a full yank!), I revisited this assembly. The lever and handle are now separate parts. The lever and handle interlock and a 4mm cap screw completes the attachment and provides strength at the joint.

Interior Grate

Just an aesthetic detail - I wanted to give add a bit of detail to the area near the based alcove of the main case where the trap door hinges are. I thought a 'grate' effect might be nice to imagine that is where the vapor gets sucked out of a cartridge. These pieces also provide some reinforcement on this area. The original Main Case parts have some holes here already for attaching this piece.
