1:12 scale Cash Register / Till from Lego

I've been looking for a modern cash register for my quilt shop for a long time.  I could only find two for sale online, a British one which wasn't very detailed and an American one which seemed rather expensive.  There is a card printable cash register on Jim's Printables, but I didn't think I could get it to look very realistic.  So I decided I would have to make my own.

Step one was to have a protracted dig in my son's large box of discarded Lego (he has now grown out of it).  After a long search, I came up with the following components.

The two bases are quite thin, only one 'bump' high.  I put one on top of the other to simulate a cash drawer, added the slanted bits to be the keyboard, and topped it with the four-bump bar, and capped off the bumps with the two smooth caps. 

Meanwhile, I was also looking for a bit of Lego to use for a credit card machine.  I didn't find anything, so I had a dig through various other junk boxes and came up with a discarded dollshouse electric plug.

I pulled out the wire and the pins, and cut the plug in half using a razor saw.

To make the sides of the credit card machine, I used one small punched card circle (the size of a hole punch for a ring binder) for the end, and cut two side pieces from a larger punched card circle.

Then I sprayed both assemblies with grey car primer.

To add the detail, I searched on Google Images under 'cash register screen' for the keyboard, 'cash register customer pole display' for the readout, and 'credit card machine' for the credit card machine keyboard.  I shrank the images I found down to the appropriate size, and printed them out on an inkjet printer.  Then I sealed them with DecoArt Multi Sealer, and glued them on using PVA glue.  I also added a poster for quilt classes to the customer side of the register, and a tiny 'crystal' to be the keyhole of the cash drawer.
