Anyone here have a 3d printer? - F-Body Road Racing and Autocross Forums

I made a tablet mount for my Firebird, galaxy Tab A, random amazon case, running solostorm. The tablet and case weigh in at just under 1.5 pounds.

Each side of the mount is 35mm wide and held to the dash with two 1/4-20 bolts, the cross bar is 25mm tall. The dash is backed up with 1/8" steel plate (should have swiss cheesed it some) with nutserts, the dash is drilled larger than the nutsert 'heads' to let the plate sit flush and the plate is RTV'd in place. The latch pivot is two #10 screws, I tapped the latch to screw them in nicely. I was going to use an o-ring or spring to keep the latch closed, but it snaps in place over the case pretty well.

I printed the whole mess with Overture PETG with 4 top and bottom layers, 4 walls, and 20% infill on an Ender 3 V2. I used freecad to model it... many times!

My main concern is either the 30+ year old dash plastic cracking or the PETG melting during the summer. The car is towed almost everywhere as the sun is coming up and the windows are open most of the day once I get there unless it's raining. The tow home is mostly after the hottest part of the day. Sometimes I'll tow the car all day long with the windows up for national events, for those days I can unbolt the mount (another reason for the backing plate, nutserts, and RTV).

Here are some pics along with other things I've printed.

It seemed to help a bit. I made another PETG part this week right on the textured bed, let it sit for an hour or so before I was able to get to it, and it popped right off with a good twist. Too bad I rushed the design and should redo it at some point! I have to say, the ability to dream up, design, then print something in a few hours total has made me a bit lazy. It feels like I would be a bit more thought out cutting and drilling than clicking and printing!
