12mm cross hare laser holder for 16.5 mm laser tube co2 laser

thingiverse

Saw someone had done crosshairs using the acrylic sheet as a holder but it just was to unstable to give me a dead center crosshair. so I started off using a balljoint design based on someone's work this was ok but kept moving. I then decided to make a new version using my own design and hinge system. it is held together with M3 hex bolts 15mm and 20mm screws you will need to print 2 of the arms and one of the body, ii used electrical tape at one end of the laser so i can align them in height. I also hot glued the lens cap when I had aligned them so they can't move but can be changed if neccersery. if our beam is not central in the mark your laser head mirror is not central I thought originally design issue but it was laser was off by 1 mm the lasers I used can be found here. https://www.amazon.co.uk/gp/product/B07PJKG1WT?ie=UTF8&psc=1&linkCode=sl1&tag=joshcreativep-21&linkId=7e4f680e68c627e982b7667106fbc5fc&language=en_GB&ref_=as_li_ss_tl jst connectors I used to join and solder 2 lasers together can be found here.https://www.amazon.co.uk/gp/product/B07PJKG1WT?ie=UTF8&psc=1&linkCode=sl1&tag=joshcreativep-21&linkId=7e4f680e68c627e982b7667106fbc5fc&language=en_GB&ref_=as_li_ss_tl
