Picatinny laser pointer mount

thingiverse

Here is a adjustable OpenSCAD design for mounting both the laser diode and coin battery with standard connector for an external switch. Assembly requires soldering wires and a hot glue gun. Edit the OpenSCAD file to enter dimensions for the specific laser pointer you are using. These are "d_lamp" and "l_lamp" for diameter and length of the laser pointer. You may need to add a little extra room to fit it properly. Use OpenSCAD to generate your custom STL file. In the USA, you can use a Class IIIa laser diode module for gun sights. These lasers do not exceed 5mW output and are designed to not cause eye damage if inadvertently viewed. They are commonly used for laser pointers (presentations and cat torture) and laser gun sights. Don't be outfitting this with a Class IIIR or Class IV laser as someone will get hurt. Do take care never to intentionally point the laser into anyone's eyes. Any respectable CQB Arena should ban you for life for not following basic safety requirements. The battery is based on a CR2032 size, which fits a common 3v coin battery, but 3.7v li-ion rechargeable also exist and should work better. The holder I use also fits a CR2016. The laser diodes typically work from 2v to 5v and draw 20mA to 30mA. Check the specs for your laser module to make sure it fits into these ranges. Output of the laser is typically regulated by the module, not the input voltage. A 1.25mm 2-pin male connector is fitted into the side for the switch. You may need to adjust the dimensions for your connector's housing. Of course using the connector is optional but makes wiring for the switch easier. You'll need two 4x30mm screws and matching nuts to attach the laser mount to your picatinny rail. This was originally based on https://www.thingiverse.com/thing:641947 for the mount and lamp design. The momentary switch mount was designed to press fit to the G&G ARP9.
