May get some photo's up on it later.
This is my first full design on my prusa-reprap, as well as my first on my CAD program. Works great! Thought about putting a switch on it, yet wanted it small and out of the way. So, this is the end result.
Did not know the springiness of the PLA plastic when i designed the clips. They printed great yet too tight to snap on my 5/16 threaded rod i made them for. So, i just powered up the old hair blow dryer and in about 2 minutes it was snapped on, then off again and a little tiny squeeze to make it a snap on and it works great. Just don't expect PLA to have any spring on an item this small. Hard stuff! ABS plastic may be different, don't know, never used it ... Yet!!
Print it slow, mine on 30mm/s, and it should do well for you.
It uses 3 tiny LED bulbs "T10, W5W, 168, 194, 7SMD" any of those should work i think. 12V White LED's. Mine i found on ebay 6 bucks for a ten pack. Shipping was USA, may find them China cheaper if you want to wait a month on shipping. Your auto parts house have them, much more though, yet i'm sure much better bulbs.
These have 7 tiny tiny LED's per bulb, yet the lite from one just would not do. They are a bit less than .6 inches below the led's on each bulb cap (the part that pushes in the outer shield) and maybe an 1/8th inch above it. So, any of those bulbs above should work, yet depending on make of bulb some may hang out, yet the .6 inch lower part size fits perfectly. They are .360 inch in diameter.
Wiring them up was a bit tedious, though i got them wired. The trick was using small gauge solid copper speaker wire and pushing the fine wire in the bulb where the bulb wire comes out of the plastic bulb housing. Wasted one bulb figuring that out. Only use very lite heat on iron or you will waste your bulb. Then i dropped a tiny bit of solder on the end of bulb where all the wires come out and it works great.
Also had to run a bit larger hole in it for the two power wires coming out the bulb holder.
Hope you enjoy! These printers ARE AMAZING!!!! Love mine! Happy Printing, Rick.
