"eTarget" A system for target practice with a Laser Bullet ***Updated***

thingiverse

I decided to repost this. I hope there are no issues with copyright or patents. Updated, I redesigned the Cell Grip L-R. I made it to fit a more standard nut. Cell Grip L-R 3 is the for larger nut. This is similar to the "iTarget Sled" used for target practice with a laser bullet. It uses your cell phone with the "iTarget" app. It will hold a phone from 65mm to 96mm (2.559” to 3.779”). This design uses a standard clipboard to hold the targets. There is also a place to hold your laser bullets in 9mm, .40 S&W, .45 ACP, .380 ACP, & .38 special. There are two "rails". They both have 1/4" holes for mounting to a stand or set on flat surface. One has a dovetail to fit an Arca Swiss ball head clamp from a camera tripod. There are also two holders. One narrow and a wide. I think the wide one works better. You will need a 3" long 10-24 screw and nut. The nut can't be larger than .312" across the flats. The nut get inserted at layer 162 at 0.2mm resolution. Once the knob is printed thread the knob with a tap then thread the screw in. Cut the head off so that the screw protrudes no more than 52mm and no less than 50mm. You will also need a 1/4-20 screw 1-1/4" or longer. Do the same like above. Cut from 15mm to 18mm protruding from knob. Depending on how your printer prints you may have to sand some of the parts down a little to fit. The "Rail" is just under 12" so you will need a large build plate for that part. For the L - R Phone Mounts I strongly recommend using 2mm Wall, Top & Bottom thickness. The knobs will need support. I printed then large side up. The Holders lay flat on their back with eTarget text facing up. The Phone Mount will need support underneath where the rail inserts. The other parts will not need support. Please Contact me if you have questions. Thanks for looking.
