Elecrow Crowtail GPS v1.0 Enclosure with Antenna Case

A two-part protective enclosure for the Elecrow Crowtail GPS v1.0 / u-blox NEO-6M module and its separate ceramic GPS antenna.

The GPS receiver and antenna each have their own base and lid. Both enclosures use four external screw tabs, keeping the screws away from the electronics. The lids have countersunk M3 holes and the bases have blind 2.7 mm pilot holes, allowing M3 screws to form their own thread in the PETG.

The dimensions were estimated from photographs. Print the bases first and check the fit before printing the lids. Clearances can be adjusted in the included OpenSCAD file.

Hardware

* GPS enclosure: 4× M3 × 20 mm countersunk screws

Nylon M3 screws are recommended for the antenna enclosure because metal close to a GPS patch antenna may slightly affect reception. Ordinary metal screws can be used for the receiver enclosure.
