JTR OEM Steel Bumper Close outs

[khockey02]

Those look awesome. Is it possible to recess that plate into the bumper or do the mounting standoffs come out too far?

I'm back in town, but buddy with a steel bumper is out of town until Tuesday. If someone can even mail me a cardboard mockup it would do wonders. As of now just kind of in the dark.

Or maybe my dealer has one on the lot...

Do you have the geometry available?
They came out pretty nice btw...
I would go with that material as it does look tough and the finish works well.

Geometry?

A piece of cardboard and a sharpie, that's all the geometry I got

Go to any "truck parts" supply house (big truck) and they will have a selection of mud flaps. Pick the material you like in the size you want, about $10 a piece.

Still working a couple years later, still look good a couple years later, and the guy I made a set for and sent to him from this forum still owes me $25 a couple years later, LOL.

Anything is possible, but making a flush fit filler panel would be very involved, likely starting with a mobile CMM. Not really worth the effort.

Following. I'd definitely take a set.

Interested as well.

CAD (Cardboard Aided Design) is the best in my opinion. That's how I'd do it (source: automotive engineer).

If you have a relatively recent iPhone, you can try the ScandyPro app. I just tried it on the engine bay and am pretty excited about it.

I forgot to do this last weekend (Cardboard model)...
Some toolboxes and shelving became available on marketplace for my garage so I rearranged and decluttered my garage for jeep mods lol.

Honestly, you could take the base image of the expensive as hell ones, turn it into a vector image, and then use inkscape to convert the cutouts to a 3d part that you can load into tinkercad, scale it to a 1:1 image, and then print away

(I've done this exact thing, for years, with various flat objects that I need/want to print. (It works for embossing, too, if you invert the part in Tinkercad)

(Note, if printing in 3d material, I'd recommend nothing less than PETG or ABS)

Those are tough resins...(Thermoplastics)
Often, these are automotive materials...(Soft Stuff)
PPO: Rigid Polymer Alloy
TPO: Thermoplastic Olefin
TPE: Thermoplastic Elastomer
TEO: Thermoplastic Elastomer Olefin
Tough stuff:
ABS: Acrylontrile Butadiene Styrene

ABS isn't as chemically resistant as PETG but it is more rigid and tougher...
PETG is good up to
Both are good materials for this application I agree.

New guy here, just grabbed a mojave.

work in plastics, Id use seaboard or starboard…uv and chemically stable hdpe. If someone makes a solidpart or similar i could run it at our shop. Throw a sheet of .25 or .375 on the router and run sets.

I am a blow\injection molding engineer as well - HDPE is pretty flexible (not very rigid), no?

In a milk jug is flexible, but at 0.25 and up, its not going to flex.

Since I dont have this bumper, and looking at the pictures its hard to tell, the earlier pics it looks like someone used ABS/Kydex and also heated to bend the edges in. Anything from the HDPE that I recommended would be similar to the metal ones that are outrageous $. You are not going to be able to flex it into the bumper.

The material is similar to the plastic cutting boards a lot of people have at home. Slightly different texture and UV stable. Doesnt bend.

woah, .250" definitely not bend.
I think if possible two indentations where the 2 bolt trusses are would enable it to sit inside the geometry vs. standing proud of it.
