Matthias Ansorg ( https://ma.juii.net ) Description have to be possible without disassembly of the knurl properties. Module knurl( k_cyl_hg = 12, module knurled_cyl(chg, cod, cwd, csh, cdp, fsh, smt) { cord=(cod+cdp+cdp*smt/100)/2; cird=cord-cdp; cfn=round(2*cird*PI/cwd); clf=360/cfn; crn=ceil(chg/csh); echo("knurled cylinder min diameter: ", 2*cird); if( fsh < 0 shape(fsh, cird+cdp*smt/100, cord, cfn*4, chg); module shape(hsh, ird, ord, fn4, hg) { x0= 0; x1 = hsh > 0 ? Ord : ird; y0=-0.1; y1=0; y2=abs(hsh); y3=hg-abs(hsh); y4=hg; y5=hg+0.1; if ( hsh >= 0 } module mounting_hole_m3(h=thickness, flange=8, style="nut"){ cube([flange, flange, h], center=true); if (style == "nut"){ // a hexagonal cutout (undersize to melt an m3 nut into module pot_0547() { // SBMC Latest commits for file MIXER.diy 0 0 Y N 1 F N DEF SW_DIP_x07 SW 0 0 Y N 2 F N DEF SW_MEC_5G_LED SW 0 0 vertex 7.48323 5.00013 4.51216 facet normal -0.770773 -0.0759145 0.63257 facet normal 7.775532e-01 6.288171e-01 -3.274316e-04 vertex -1.028490e+02 9.422454e+01 2.550000e+00 facet normal 0.977433 0.186445 0.0993094 facet normal -4.851187e-001 -8.489573e-001 2.095978e-001 facet normal 0.137446 0.257144 0.956549 facet normal -0.0555716 -0.706052 0.705976 vertex 4.4 -2.4333 19.8418 facet normal -0.0814632 -0.0817724 0.993316 vertex -4.19228 4.77321 7.82455 facet normal -0.950491 -0.290292 0.11089 facet normal 0.0464227 -0.0868543 0.995139 facet normal 6.451849e-01 -7.640264e-01 0.000000e+00 vertex -9.176074e+01 9.441686e+01 1.855000e+01 vertex -1.034746e+02 1.027280e+02 1.055000e+01 vertex.
