This is a design I created for a Uni project, I hope you all like!

The bottom has an 8mm hole for a cable to pass through, the middle has a 30mm hole for a bulb fitting. I used PLA to print the whole lamp and used superglue to glue the middle part to the bottom, the top slides on so the bulb can be replaced. I would recommend a warm light which isn't too bright. The top is printed at 100% infill to give the best effect, or maybe even with honeycomb infill on the top!

I haven't got a link to the exact electronics I used but I can link very similar electronics, the bulb was similar to this https://www.wilko.com/en-uk/wilko-led-bulb-classic-bc-470-lumens-3pk/p/0465929, and the fitting was similar to this https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F113209371546, I just used some 2 core cable I had lying around and a standard UK plug, the fitting screwed on well to the middle part of my design.

UPDATE: I have uploaded files for if anyone wants to mould the bottom part, I have uploaded one big base which I used, however I found it wasn't easy to remove the concrete. This is why I have uploaded a version which has been split in half with a cut out for it to be slotted together, I would recommend printing the top half with some kind of semi-flex filament so it has some flex when coming out. The side part of the mould needs to be printed twice as it is only half and bolts together with m5 bolts, this then slots over the bottom part of the mould. I used epoxy to glue the middle part on to the concrete base. If anyone has any questions don't hesitate to ask or if I have missed anything please let me know.

I have included a photo of how I attached the light and the fitting as well.
