Stage-inspired LED Spotlight

IMPORTANT!! turn the parts as shown in the picture from Cura (yellow parts) before printing! That way you don't need any supports.

Update 06/01/2018
Added a bigger version of the back end to accommodate electronics. This version also has a modified front end in the two lengths, where the inner diameter is increased to 22,5mm to accommodate for this lens: https://www.ebay.com/itm/251962202709
Please note that I have not tested this update myself as I'm out traveling so please let me know if there is any problem with the design.

Chad_R made an addon to secure the LED in the cabinet:

I wanted spotlights for my 3D printer cabinet so I decided to draw stage-like spotlights in miniature. I use LED's from Hobbyking and run them on roughly 130mA without overheating.

Note! this LED is no longer available from Hobbyking. I don't have any recommendations because I don't want to post links to something that I haven't bough
