Kossel Tennis Ball Feet - Remix

thingiverse

I've been using JamesWhite's feet for some time now, but I've been annoyed that (a) the shrouds almost touch the surface the printer is sitting on and (b) the tennis balls fall out whenever I pick up the printer to move it (which happens quite often).\r\n\r\nSo, off to OpenSCAD to recreate this as a parametric design! Please find attached:\r\n\r\n* kossel-ball-foot-v2.scad\r\n * The cup diameter is adjustable to fit whatever tennis balls you have on hand.\r\n* m4x5-bush.scad\r\n * M4 bushes, which might be necessary if your M4 bolts are too long.\r\n\r\nTo achieve the best stability for your printer, use the smallest tennis balls available (they will be set wider than feet with larger tennis balls). In the picture:\r\n\r\n* 45mm Korbond Mini Tennis Ball designed for small dogs\r\n* 62mm Korbond Tennis Ball\r\n* 64mm Hyperpet Tennis Ball (for their elastic-powered Ball Shooter gun)\r\n\r\nMeasure your tennis ball's diameter with vernier calipers and use this measurement for a tight fit. Add 2mm for a looser, but still snug, fit.
