Lip Balm Holder

A bit of tinkering with the OpenSCAD code that produced the DeoxIT bottle holder delivered a place for the cylindrical objects we use just before cycling:

Lip Balm Holder

The tubes are 1.5 diameters tall, minus a skosh, so the cylinders stand neatly inside and don’t want to fall over. I added about 1 mm clearance and you could taper the cylinder openings for E-Z insertion, although we can eke out a miserable existence with this thing as-is.

It works exactly as you’d expect:

That big stick in the middle is actually skin sunscreen, not lip balm; let’s not get all pedantic. The intent is to keep those cylinders from rolling off the shelf and falling into awkward locations, which this will do.

The OpenSCAD source code is strictly from empirical:

// Lip Balm Tube Holder
// Ed Nisley KE4ZNU - July 2015

//- Extrusion parameters - must match reality!

ThreadThick = 0.25;
ThreadWidth = 0.40;

function IntegerMultiple(Size,Unit) = Unit * ceil(Size / Unit);

Protrusion = 0.1;

HoleWindage = 0.2;

//------
// Dimensions

Tubes = [18,26];			// tube diameters plus clearance

WallThick = 2.0;

Plate = [1.5*(Tubes[1] + 2*Tubes[0]),2.5*Tubes[1],IntegerMultiple(2.0,ThreadThick)];
PlateRound = 5.0;

NumSides = 8*4;

//- Build it

	hull() {
		for (i=[-1,1], j=[-1,1]) {
			translate([i*(Plate[0]/2 - PlateRound),j*(Plate[1]/2 - PlateRound),0])
				cylinder(r=PlateRound,h=Plate[2],$fn=NumSides);
		}
	}

	translate([0,0,Plate[2]/2])
		rotate(180/NumSides)
			difference() {
				cylinder(d=(Tubes[1] + 2*WallThick),h=1.5*Tubes[1],$fn=NumSides);
				cylinder(d=Tubes[1],h=1.5*Tubes[1] + Protrusion,$fn=NumSides);
			}

	for (i=[-1,1])
		translate([i*((Tubes[1] + Tubes[0])/2 + 1.0*WallThick),0,Plate[2]/2])
			rotate(180/NumSides)
				difference() {
					cylinder(d=(Tubes[0] + 2*WallThick),h=1.5*Tubes[0],$fn=NumSides);
					cylinder(d=Tubes[0],h=1.5*Tubes[0] + Protrusion,$fn=NumSides);
			}

    This is exactly the sort of thing 3D printing is for. Come up with a quick idea, knock it out, get on with your (now slightly improved) life.

      Some of the guys on the M2 forum could apply finishes to make it look like mutant bones, aged and weathered just like an archaeological discovery, but we’re satisfied with straight-up magenta PETG.

      Low expectations, I suppose… [sigh]

    you must find that the spray sunscreen is as effective as the lotion type?? I’ve always wondered, seems like you’d have to apply more due to the different variables: wind, aim, etc. where as the lotion type goes exactly where you put it w/o inhaling a bunch of butane or propane, or whatever they use to propel it….

      Nope, that big middle tube contains a solid stick of sunscreen with a twist knob on the bottom.

      We don’t like aerosol anything, for exactly the same reasons as you!
