Stand alone street lamp - no supports

Parts other than 3D printed parts are as follows:

A 5mm LED which is soldered to a CR2032 battery holder with switch obtained from Amazon or elsewhere plus a CR2032 battery which should last in excess of 10 hours according to what I have read.

Now to the 3D printed parts ….

As well as the “BASE_INNER2” which is used to support the main lamp body, I have included three different base types:

BASE_REMIX : a simple base into which you glue the inner. With this base, I used double sided tape to hold the battery holder.

BASE_REMIXwith holes : As above but with gaps on each side should you decide to wire up several of these models and power them all from a single source

BASE V2 : My final version which attempts to hold a CR2032 battery holder and switch - items I found on Amazon. 

street_lampV2 is my final version of the street lamp. It uses a couple of pins to hold the LAMPTOP V2 which carries corresponding holes. You will see that the hole which runs through the lamp post to carry the wires looks blanked off - this is intentional as you cannot print holes in mid-air - the “platform” towards the bottom of the inner lamp post is only 1 layer thick and is removed with an 8mm twist drill quite easily once printed.

All parts are reasonably tight so apart from gluing in the base inner, parts will push fit. (Depending on how accurate your printer is, you MAY need to sand some of the joining pieces to make them fit - I didn't).

DIFFUSER5_2 was designed to accommodate via a push fit, the LEDs which I also found on Amazon. (Labelled as ‘warm white’). I found that despite being labelled as 5mm, not all LEDs are indeed 5mm in diameter so again, a bit of tweaking may be needed with a drill bit or glue, to keep your LEDs in place. (The holes in this diffuser were designed to be 5.2mm in diameter which suited the LEDs that I had bought).

The photo by the way shows what I was using these lamps for - I have published the snowfield here as well as links to most of the other parts in my winter scene.

Final note - although I said that I didn't need supports, there is some unavoidable bridging required at the top of the street lamp to form the holder for the top - this printed reasonably well for me although you may find the odd stray string of filament when you come to make it.

The original from which this is derived suited my needs perfectly as I was looking for a model street lamp / street light to go alongside a Christmas scene that I was assembling and pictured here.

However…. I did not want to control the lamp electronically, I just wanted to fit a 3V lithium cell, battery holder and switch beneath the base. The original also is a little weak when it comes to some of the features which need supports. By this, I mean the ‘rings’ which are a feature of the main lamp body as well as the interior hole which I have commented on already.

As well as reworking the main lamp body to print without supports I removed the need for supports when printing the lamp top and the diffuser.
