PLA bearing fully customizable scad

thingiverse

Greetings! This is a straightforward PLA bearing SCAD script with a full customizer ;) Begin of the script : `// Configuration of script bearing_length = 24; // mm - length of bearing bearing_outer = 16; // mm - outer diameter bearing_inner = 8; // mm - inner diameter // Fins (inner cutting elements) fins = 14; // # of fins fin_dx = 3; // mm - distance from center to fin fin_len = 5; // mm - length of fin fin_d1 = 0.0; // mm - initial diameter of fin fin_d2 = 1.2; // mm - final diameter of fin // rotation of each fin fin_skew = 70; // degrees - skew angle of fin // Side grooves gr_on = true; // yes(1) or no(0) gr_dist = 3; // mm - distance of groove from end gr_depth = 0.5; // mm - depth of groove gr_width = 1; // mm - width of groove` It's almost self-explanatory. All you need is to load PLA_bearing_gobo.scad into OpenSCAD app and set up your own numbers/dimensions of bearing. Have fun. VERSION V2: SDJMcHattie provides some improvements to the thing - go grab _v2.scad version !! VERSION V3: After many tests I came somewhere closer to "ideal" bearing (in fact, pretty far from ideal, but closer ;) Version V3 creates linear bearing with spherical cutout of top and bottom of bearing cylinder, and impress text on a side with inner diameter. It uses text_on.scad library - credits to https://github.com/brodykenrick/text_on_OpenSCAD and original authors. It looks like version 8.13mm is the best (fits out-of-the-print without postprocessing). Bearings mounted and continuously testing. text_on.scad / text on .... This is a rework of version 3 of write.scad to use the new OpenSCAD internal text() primitive. All credit to Harlan Martin (harlan@sutlog.com) for his great effort on the original. Great thanks to t-paul (and the OpenSCAD dev team) on adding the new text() primitive. Print Settings Printer Brand: RepRap Printer: Prusa i3 MK2 Rafts: No Supports: No Resolution: 100u Infill: rather not applicable ;) How I Designed This See original source project for this remix - I was disappointed because it uses STL file as a source of "fins" inside the bearing. I read some OpenSCAD docs and tuts, and wrote this simple script which is more flexible.
