This is a wax seal was made due to most I've seen required smaller hands and/or many supports required to build the part. By building this from the base up, you can get a good clean seal at the top.
Used PETG filament for temperature resistance, but PLA might work just fine. Use 8 top layers for smoothest possible embosses.
Build from the end up, no supports needed. If using a Core X-Z printer, you'll probably need a brim initially.
The author marked this model as their own original creation.
