one twisted ring from one twisted guy

here's one for you all to play with...make a finger sz crv and measure it...extrude a 4mm sguare the length of the crv and fillet the edges...turn on history and flow to the finger crv...now twist the extruded square infinate on..then cage edit the twisted square to get a wider shape on the top of ring....then wire cut 1/2 (the lower half) of the twisted extruded square.... history will do the rest....scale down to the size you need......then send the stl to the mill ...or your printer!...have fun!

im trying to figure this out whilst i sit here with my redbull and cointreau and my toffee pop (google it). Either I've already had too much to drink or I'm missing some cruical step. . . .

draw a line from center of the sq the same length as the circle...boom...extrude the sg from end to end of the line..boom..now turn on history..boom..flow the extruded sq (flow along crv) to the circle ..boom..now twist the extrude sq check infinate ...boom..now turn on cage edit for the extruded sq use 4points each x,y,z,...boom..now here come the fun part ...boom boom...top view!, grab the two edge points on the top and bottom and scale 1d from the center to widen the top of the ring...boom...'optional'..you can also then grab the one end point, top and bottom and each side left and right (front view) and scale the ends out a little to widen the bottom of the shank...boom...now use the line you drew for the extruded sq and wire cut the bottom half away of the extruded sq...boom, then scale the ring to the size you need...boom...now send it to your printer boom.. give it a try and post the results if you have anymore problems let me know which boom or boom boom your mising I could try and make a video... but don't wait!..thanks

looks good...... also try with a chamfered sq instead if a filleted sq..for a different effect.... and on and on ...now add the your twisted wire...how was the video? any suggestions?

the video was very good. I haven't ever used wire cut before so i think i needed to go over that bit a few times before I got it. some very handy tools that i never really used. thank you! also tried variations of it with different profiles - i used an oval, as well as a square with concave edges. also did one with 'beaded' rows which worked well but i think the edges become too thin to either print or cast.

see how that bottle of muscato got your creative juices flowing.....now don't smoke anything (unless your doctor prescribed it for you) or you'll really come up with some wild designs

it may be because the crvs you extruded are not a solid the piece is open on each end...try again!...having any fun yet? also watch your cutting direction....
