I recently received a 4G pocket wifi modem ( HUAWEI E5576-325 4G LTE Wi-Fi Modem ) but for me, the best place to get a correct 4G signal is right outside my office window. So I designed this little suction cup basket to stick it to the pane of my windowand having the best 4g signal as possible.
A small opening below to allow a power cable to pass through if necessary, and an opening in front to see the diodes, et voilà !
Printed in PLA. For a best result i used support (tree) and irroning, but i think you can try without if you are brave enough
you also need two suction cup (20 mm) (https://www.amazon.fr/gp/product/B0BBS6V2G7/)
dimensions :
11cm long
2 cm wide
6 cm high
Have fun, make thing !
