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.

Nice project. I don't think you'll have any problem with PETG melting. If you had used PLA, you would have a problem.

I've been doing 3D printing for 7 years.

Thanks, I just got an Ender 3 V2 in January and had to teach myself Freecad after 15+ years of not using any 3d software (they've changed a lot in that time!)

I thought I had all my settings dialed it great, but I fooled myself by only printing larger things with carefully placed overhangs. I tried a few print in place toys for my son and had nothing but problems, either poor adhesion or overhangs that curled up then got hung up on the nozzle and came loose.

Have you tried printing ABS or some of the more exotic stuff yet?
Do you have a good source for learning tips and tricks? All I found are some facebook groups but they're overrun with really new people asking the same questions over and over because searching on Facebook is a nightmare.
