You're trying to seal Voron Trident, you've already sealed everything with aluminum foil tape, and there's still heat and ABS smell leaking out somewhere. Try these plugs designed for the top 4 corners.
For a friend I made a variant of the seal for the Voron V2.4. Unfortunately the V2.4 still has huge holes around the Z motors. I don't own a V2.4 myself and don't plan to. I've tried to seal these holes with another model, but I don't own a Voron V2.4 and haven't found enough testers to help me tune the tolerances yet. But this sealing plug will hopefully help a bit with heat leakage for starters, although it won't get rid of the ABS smell like I was able to with the Trident.
Based on the Voron Trident model from https://github.com/VoronDesign/Voron-Trident and Voron 2 model from https://github.com/VoronDesign/Voron-2.
The author marked this model as their own original creation.
