LED Tealight Holder 3/8" Dowel Rod

thingiverse

Final iteration of a fun learning project. A teacher needed to put a battery operated LED tealight onto the end of a long 3/8" dowel rod. Since this is for small children glue or tape would not survive long enough to practice and actually still have them for three days of a show. The needs were: had to be sturdy enough to be reused frequently and even dropped often. black space for the on switch as little assembly as possible (i.e. glueing, drilling, screwing) cheap A 2lb spool of ABS was $32 To create 35 of these I used 276 grams of material... $9.73 or about 28 cents a unit. pretty cheap, I guess I could have cut down on some of the material in the cup but then I don't think it would have survived as well. The addition of the hole for the switch made it so that each print had to be trimmed. the first three layers printing with no supports were always a bit messed up. But on this final product there is no glue, drilling, or anything additional. You just push it onto the end of the dowel rod and the tiny ridges inside keep it tight. Same goes for the cup for the tealight. The addition of a small interior ring keeps the tealight secure. Final STL and Open SCAD file are on here. I just learned SCAD for this project so if someone wants to give me some pointers I would welcome it!!
