Pseudo Nixie tube mini version without copper pillar

After the program is adjusted, we will add the WeChat distribution network. Now we are still short of acrylic boards. I made proofs on the 2nd and haven’t shipped them yet on the 13th.

Special effects have been added. The water flow from 9 to 0 will stop at the end of the hour, minute and second.

The boss is missing 4 sets of digital acrylics 

Acrylic proofing is so expensive.

The acrylic is scratched and it hurts. The 4 sets of numbers I bought newly have no protective stickers. They were all torn off and the numbers in the first four sets are all blurred. Only the two sets on the right are not clear.

The screws are of m2 size, and the height should be 11mm. Just double-pass is fine. It is best to buy an m2 nut. Of course, it is up to you how you choose it.

Also, the typec power supply interface on the back will hold up. If you have the ability, you can change it to the side power supply. I don’t have much time here so I won’t change it.

Some students left a message saying that they could not open the DXF image. I uploaded a 2010 version of DXF here.

I remember that AUTOCAD2010 should be the most commonly used, and the interface has changed in previous versions.
