The settings used may not be all that important, I used these settings in order to get the supports so they were very easy to remove by hand. I used dissolvable PVA supports, but just pulled them off by hand.
You could easily use regular supports and cut them out by hand. You may need to drill out some of the holes if your supports go into the holes.
I setup Cura to only create supports for overhangs over 75 degrees, this prevents supports from going inside some of the screw holes.
Wall Thickness: 1mm
Top/Bottom Thickness: 1mm
Infill Density: 20%
Generate Supports: Yes
Supports: PVA or PLA
Support Placement: Everywhere
Support Overhang Angle: 75 degrees
Build plate Adhesion: Yes
Step 1: Add Nuts into the front of the case
Using a soldering iron melt the nuts into the print. Repeat for 4 nuts to hold the circuit boards in place, and 3 more to hold the back on.
Note: Alternatively you can use M3 screws directly into the plastic, but these nuts will allow you to disassemble the clock many times without worry of stripping the plastic.

Step 2: Install 22 M2x5mm scews in the front of the case
Screw these directly into the plastic. These screws perform no functional purposes, they are simply part of stylizing the clock

Step 3: Install the SET and ADJ tack switches

Step 4: Install Steampunk Gears
Using M2x5mm screws and Steampunk Gears, arrange them in your own artistic way. There are 8 holes on the top and sides to allow you to customize and stylize your clock.

Step 5: Install Electronics
Install the electronics, pay special care to align the two small neon colon lights. Secure in place using 4 M2x22mm screws

Step 6: Install the Buttons
Install the two "Nixie_TubeButton??.STL" inside the back of the case, sand roughness if required to ensure smooth operation. Test fit the back to verify the tack switches are working correctly.
Step 7: Install gears to decorate the Buttons
Install two small Steampunk Gears using two M2x5mm screws on the buttons to decorate the Buttons

Step 8: Screw the Back to the Front
Using three M2x5mm screws screw the back to the front of the case.

Step 9: (Optional) Install not on power jack
If you wish you an install the lock washer, and nut on the power jack using a small screw diver to install the nut.
(Optional) Install Power Socket Nut
Step 10: (Optional) Sand / Paint & Reassemble
This is entirely up to you, but if you wish to give the clock an aged metal look:
- Completely disassemble
- Sand and Smooth the model to remove any 3d printing layers
- Prime and Paint
- Apply a wash to add the appearance of dirty and shadow in the low spots and panel lines
- Apply a clear coat
(Optional) Sand + Glazing Putty + Primer + Sand to get a smooth surface
(Optional) Copper and Bronze colour coats
(Optional) Age the copper and bronze with brown, black, and green washes
(Optional) Clear Coat
This object was created using Solidworks, I took some time to add small details that I hoped would show up nicely when applying washes to the model.
