C64 Ultimate IO Trim + Bộ nút Menu/Freeze/Reset

Based on an existing user port trim panel design, this one has been tweaked slightly for a better fit on the C64U, and I've added a cassette port cover that provides space for 3 micro tactile switches for the optional menu/freeze/reset buttons.

I decided that it was extremely unlikely that I'd ever connect a tape deck, and the opening for the cassette port provided enough space to add the buttons without messing with the side panel.

It uses 4.5x4.5mm switches with fairly long button stems. I think mine were 4.5x4.5x7mm. Buttons will need holding in place with hot glue (may revisit this, but it was easy and added a bit of strain relief to the small solder joints)

Prints nicely with the outer face down on a textured build plate. It will need supports, and 'normal' works better than tree supports, at least when printing in PETG. Came out nicely on a Bambu P1P in transparent PETG. (For transparent, print it solid, with lots of top/bottom layers to avoid a visible infill pattern)
