This is a small enclosure for a GPS Module and antenna. It has a suction cup to stick it to a window for good reception. The enclosure was designed to fit this module and antenna: https://www.amazon.com/gp/product/B084MK8BS2/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 but may work for other GPS modules and antennas.

The suction cup is a 30 mm base from this: https://www.amazon.com/gp/product/B073S5TX8W/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1

The cable holder is a PG7 found here: https://www.amazon.com/gp/product/B07GJDYGP5/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1

All the screws (5) are M3x6 mm.

I added a dab of hot glue to the antenna to hold it in its pocket in the lid.

It might be interesting to print it in clear filament as the red light on the module blinks the 1PPS signal when it gets enough satellites, and being clear would allow you to verify it has a signal lock.
