6-digit nixie clock

thingiverse

This is my first 3D design to learn Fusion 360 - I do not feel responsible if something does not fits, or I made it unaccording to CAD-design best practices ;-)Around 20 years ago I made 6-digit nixie clock. Recently found it my basement and refreshed by designing this new look and by replacing old Microchip 16F84A microprocessor with ESP32, which allowed me to use NTP for syncing time :-)Presented clock uses Dolram LC-513 nixie tubes from 1984, but similar ones with same or smaller size should fit. I also use stands for my tubes - extra mounting holes in front panel are to mount them (could be hidden, but IMO it gives the look extra touch).Body:Best to print back-wall down. Venting holes on top are covered with a slim layer of filament - can be cut-off afterwards with scalpell. On a back wall there is a mounting hole for old-style radio HV connector "8" - added it as I was able to mount 12V PSU inside the housing.Inside you'll also find two rails for PCB mounting.On the bottom there are two slots for mounting legs - should help with proper positioning before glue is applied.Front PanelA bit smaller than in-body diameters, so it should fit perfectly inside. If not - a bit of papersanding might be required. Mounting holes designed for M3 socket-head screws (to mount tubes stands). I use stainless-steel 20mm-long screws. There are also 2 slots for dots (small neon lamps mounted in stainless-steel LED housings).LegsYou need two pairs. Should fit the slots on the bottom of body. If not - a bit of papersanding can fix it (depends on your printer accuracy).SpacersI needed 12 of them to position tube stands in a proper distance to front panel. If I'd like to hide lamps deeper or expose them to the front, spacers can be replaced with shorter or longer ones.Everything printed with PLA.Black one is standard blck, brown is "wood-alike" - looks great with nixie :)
