A duet wifi/ethernet case designed to attach to a right angle section of 3030 extrusions, also has countersunk holes to attach a 60mm fan for some active cooling.
The bottom right pin is used as a locator pin as there might be a right angle bracket behind that for your setup. Each other hole is designed to be screwed directly into the plastic with either an M4 tap or self tapped with an M4 screw, if you want more security you can use a hex lock-nut/nut when it pokes out the back.
The holes provide decent cable acceptance areas but if it's too tight feel free to let me know.
This case was developed with the Duet Ethernet in mind but should support a WiFi just fine, i don't think a board using the DueX expansion boards will fit but feel free to try
The lid is a simple push fit, the bumps on one side are more pronounced than the other, as the case has lateral give just put the thicker bumps in first and then slightly flex the case to snap in the smaller bumps.
Any settings are ok, can print fine without support
