Was looking up laser sight options and man, they are either huge or very expensive for a quality one. So after a week of prototyping on my 3d printer I've come up with this little unit.
It has windage and elevation adjustment screws which are surprisingly sensitive. So far the build feels sturdy and I am very optimistic about maybe going to production level quality - but I have yet to do a range test.
Down the sights
Attached to my Ruger SR9 for size comparison.
It is a rough demonstration prototype so electrical tape to hold in the batteries and the screws are pretty protruded, overall not that pretty. Dimensions are 25mm wide 33mm long at 20mm high. This was printed as two separate units, one as an adapter for the pic rail, and the bottom compartmentalized for all the internal wiring. Besides the 3 adjustment screws at the front, there is that huge one on the left hand side to turn it on. I figure it'll be easier to access offhand, but reprinting on the right hand side can be easily done if that ends up being a better option. Had to settle for this kind of an ON switch because rocker switches and slide switches I've looked up are absolutely HUGE. They contribute more to the size than any other component. This easily cuts down on size and because it's such a simple item, less chance of component failures.
One thing I could really use some help with, especially from all the gentlemen who have been tinkering for ages, is the elevation adjustment. Unfortunately the plastic on the bottom of the second unit is extremely thin at only 3 mm. The screw does a great job zeroing in but after several minutes of working the action repeatedly, the threading strips the plastic pretty badly and it ends up coming loose so loss of zero. Is there anything that I can use that might reinforce this area? I was thinking of embedding a nut into the plastic but can't wrap my head around securing it in place well enough.
Anyways, I have parts for another 9 units so hopefully the design can be further cleaned up. Eventually, if there is enough interest, I'd be happy to send them out to any (few) volunteers who want to help test perhaps with different calibers.
Input greatly appreciated![[smile]](/xen/styles/default/xenforo/smilies.vb/001.gif "Smile [smile]")
