Dual line laser pointer holder for chinese laser cutter
thingiverse
My reasonably priced 40W laser cutter from a Chinese manufacturer ('ecpur') boasted a red cross laser pointer for accurate positioning assistance, yet its mounting was notoriously tricky and resulted in an oblique placement, causing the focal point to depend significantly on object height. This thoughtful design substitutes the original laser pointer with two sleek line-type laser pointers oriented at 90-degree angles. Once correctly positioned, their precise intersection harmonizes perfectly with the cutting point across various object heights. To enhance user experience, these adjustable lasers are embedded within durable ball joints, making it easy to adjust them for optimal alignment. Specifically designed for 12mm diameter laser pointers, affordable and reliable models can be easily sourced from China on online marketplaces like eBay at reasonable costs. --- Instructions Thoughtfully crafted in OpenJsCad for the user's convenience, modifying this design requires merely editing the .jscad file and visiting http://joostn.github.io/OpenJsCad/processfile.html to obtain high-quality STL files with ease.
