Parametric Slide

thingiverse

Customize this slide and carriage to your own specification, just four parameters to alter. I'm still learning as it's only my second attempt at writing script in OpenSCAD. I've made a small one as a test (see photo). I printed the slide first then the carriage with a 0.2 mm gap which fitted okay but was a bit sloppy, so I printed another with a 0.1 gap and that worked out nicely. I'd like to add some bolt holes for attaching things and possibly an option to add a locking device to the carriage, also maybe a lead screw. I'm also new to 3D printing - my printer is a GEEETech i3 (kit) using PLA filament with a nozzle size of 0.3 mm at 200° and bed temperature at 65°, layer height set to 0.1 mm with 100% infill.
