Description
This clamshell style enclosure is custom fit to the Lizusidtsy AD310 450W 3-way passive crossover network, as found on Amazon. It's something I designed for a friend and figured I would share it here.
The enclosure bottom has four M4 X 6mm heatset inserts that need to be installed. They should be installed fully so they are flush with the bottom of the enclosure. Four M4 X 50mm countersunk screws are all that is needed to hold the enclosure together and crossover board in place.
The enclosure is 51mm high, so the screws should be almost flush with the bottom and brass inserts.
I printed them oriented with the flat surfaces on the build plate, as shown. No supports are needed, and I used Hatchbox black PETG.
Enjoy!
