Courtesy of Dion from Holland, here are pictures of neat and compact 3D case design of a geiger clicker circuit based on the HV module and si-29bg tube

 Dion has gracefully provided these nice pictures of the enclosure. It is HV module based clicker circuit and si-29bg tube. On the top you can see the potentiometer knob which is used to switch the device on and to regulate the volume of clicks. Dion says he used a generic PAM8403 pcb from aliexpress.com and a speaker.

To compare the size to the stock 3D printed enclosure:
