3d printed flip bumper mount
 

the test truck for the airbag setup also has a texas bumper that can scrape up ants, so i thought i'd try a flip bumper. the first version will need to be printed completely. but i'm going to try to make one that requires a couple of modifications to stock parts. credit to 802 at thingverse for the bumper, Neophyte at thingverse for the original hinge design i modified, and Steen Winther at grabcad for the mount, the servo is a pico servo from one of my micro helicopters. pics of the files for now, test parts are printing. i didn't want just a simple piano type hinge, so hopefully this one lets the bumper swing up and out a bit

if all goes well, this is the plan:

take off the stock front bumper mount, then print this bumper piece

print the new front bumper mount with the servo mounting and hinge points

print the links

That's AWESOME! Have you acquired & placed all the files in one downloadable package? If so where? I have a friend that has a bumper with low ground clearance, that I'd think would love to have one of these!

well version 1 complete fail... lol

the links are smaller than a penny and won't hold up to the stress, also the servo needs to move down 15mm to clear the steering and shift servos

version 2 was done as a conventional singe point hinge, but it runs into the same problem i thought it would, there'd no room to tilt the bumper without hitting the body, so it's back to the drawing board for the 2 point hinge. the bumper needs to drop a bit, then flip.

i started with that one, it was on sale for like 150 one day so i bought it, realized after like 2 prints it wouldn't print what i wanted, so i sent it back and got the select

Yah I'll be getting a newer bigger one at some point . Originally I started out with one of those Anet A8 clones that you have to put together , I was never really impressed with the print quality , I stumbled on the Mini Select on Kijiji and it peaked my interest , I researched it and was pleased with what I read so I went ahead and bought one . Loved it right away , that was V1 and I found a V2 also on Kijiji , not too impressed with it , it has a few minor bugs . I plan on using them for a little while longer , save up a few bucks ,sell them and buy a bigger better one . But locally . I found a place about 20 mins away that sells makerbots and others
