This is a remix of https://www.thingiverse.com/thing:2844013 which is itself based on several other models.

The following is changed:

• Scaled the width of the models to 101%
• Deepened the indentations of the ports by 0.5mm
• Made the bottom 75% (approximately) of the case much thinner, saving material.
• Added feet to the bottom of the case so the bottom of the Pi is cooled better
• Added rails to the side of the case for mounting on an Ender 3 (v2) or printer that uses the same extrusion profiles
• Increased the connector hole sizes to ensure that cables always fit and alignment is not a problem

No bolts or nuts are needed for this case. The lid/cover is held in place by friction and the ports.

The rail on the side of the case is optional, but it's ideal for mounting it on a 2020/2040 aluminum extrusion v-slot profile. This includes the Ender 3 (v2).

The model with half a rail makes it possible to mount the case under the LCD panel.
