Nixie clock case, 3d printed for In-14 tubes

thingiverse

This 3D printable case is designed for a Nixie clock featuring IN-14 tubes. It was made to complement a QTC kit purchased on eBay, although the specific listing is no longer available; another source can be found at http://www.pvelectronics.co.uk/index.php?main_page=product_info&cPath=21&products_id=71. The creator has no affiliation with this seller but had a positive experience purchasing parts from them. Although laser-cut cases are available, no 3D printed versions existed at the time of creation. Using Tinkercad, the designer shared both an assembled table and individual files for printing convenience. They chose clear ABS filament for their print, using a 0.3 layer height with 100% fill to maintain transparency. Lower fill levels may work as well, except for the small spacers on the lid. Assembly requires four M3 nuts captured in the feet and four M3 x 32mm cap head screws. The lid attaches directly to these screws, while the board fits snugly into place with LEDs and buttons aligned before being pressed down. Tube sizes may vary slightly, necessitating minor adjustments. The case doesn't accommodate the GPS aerial socket included on the Nixie board; users requiring this feature must modify the design or drill it post-printing. Overall, the project is not inexpensive but offers a satisfying DIY experience with a pleasing outcome.
