PLA bearing fully customizable scad by Gobol

Last crawled date: 3 years ago

Greetings!
This is simple PLA bearing SCAD script with full kastomizer ;)
Begin of the script :
`// Configuration of script
bearing_length = 24; // mm
bearing_outer = 16; // mm
bearing_inner = 8; // mm
// Fins (inner cutting elements)
fins = 14; // #
fin_dx = 3; // mm - distance from center
fin_len = 5; // mm
fin_d1 = 0.0; // mm
fin_d2 = 1.2; // mm
// rotation of each fin
fin_skew = 70; // degrees
// 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`
is almost self-explainable.
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./
