Learned a new 3d printer trick

My fav “tool” to make with my printer is drill guides. Here’s an example of a drill guide I made for a vent hole with .375” radius in each corner.
I also printed the honey comb mesh while I was at it.

Good idea!
 
I press drill bushings into 3d printed trim & drill jigs all the time for work. Most jigs last a few cycles, unless the drill bushings heat up from improper drill angle, clogged chips, or a really deep hole that causes heat buildup in the drill bit.

For high temp lamination molds I’ve used Ultem For 250f+ cure cycles for carbon fiber/epoxy prepreg. I’ve made dissolvable mandrels for complicated bifurcated ducts and all kinds of cool shit I can’t show pictures of.

I’ve even made quickie changes to wind tunnel models leveraging 3D printed bits. There was a fuckload of filler, primer, and hand sanding, but fuck, it’s a fast solution in a pinch.

Also made some 3D printed D44 knuckles to proof a billet concept…

There's a couple of companies that make these tube contour gauges for $50-60 (not including laser). I'm cheap, so I drew my own up in fusion and will be using 3/32 tig filler rod. Rubber band keeps tension on the rods, and the insert holds a $15 shotgun laser bore sight, so I can aim at the other end of the tube junction. The fits are pretty good right off the print bed, but I want to dial them in a bit more. Once I get all of the fits just right I may sell them as a kit for $25-30 with laser included. I may be able to get it down to $25 shipped.
