3D printed caps for interior door handle bolts

[Brick Row]

Hi everyone! I just finished designing and testing some 3D printed caps that fit over the bolts on the interior door handles. I don't mind the industrial look of the bolts but figured I'd give it a shot and see if I liked having them covered better, and I think I do. I made prints using a couple of different colors, some on a textured plate, others on a smooth plate which I think looks the best. I don't have a filament color that is close to the door colors for a really seamless look but black actually looks pretty OEM since the top of the handle is black. The translucent blue actually works pretty well with the gray door panel.

Anyway, before I post the files publicly I wanted to see if there are a few people here who can print them and see if they fit well for you. The dimensions are very small and the room to fit anything around the perimeter of those bolts is very tight, so sizing tolerances are pretty important (I also have a couple of bolts that are slightly off center, making the fit even tighter). I intend for them to be printed with PETG since it's going inside a vehicle but I did also test with PLA+, the PLA prints are a little tighter since PLA doesn't tend to shrink as much as PETG but the PETG prints also go in snug. I'm using a Bambu Labs P1S and they should be able to be pressed in with a finger, and I'm able to remove them with the tip of a knife with a bit of careful prying.

Let me know if you want to test it out and I'll send you the 3MF file or the STL if you prefer that (and I'll include my recommended settings).

And just for the heck of it...gold may be a bit gaudy, but I actually kind of like it. Did I just increase the value of my Maverick?

I like them! Great job?
This may be the thing I need to nudge me to buy a 3D printer!
Can you tell me something about the printer? These look really good. Nice work.

The Bambu Lab P2S Combo is a fully enclosed powerhouse built for advanced hobbyists who want to print engineering-grade materials safely at home.

I just ordered a roll of orange filament yesterday that will be here sometime next week. I've not bought this specific color before so I don't know how well it will match but will print some caps and post a photo of them in my truck (I'm guessing the orange in the 23 XLT and 24 XLT are the same).

I would like to print some for my truck. I also have a roll of Overture Orange PLA and would be willing to print some and post photos. I have a 2023 Lariat.

They're black with the BAP

I think my FX4 are black as well but my door panels are that slate blue. Look fine to me

Matt. Sent you a PM. Would like to print some also.

I really like the BAP look

Not the best pic but mine on the FX4 are black too. I asseumed they were all black

Me too. I didn't know about the silver bolts

Just printed up a bunch of them Thanks for the file, had to do it in PLA don’t have any PETG on hand. We will see how they hold up down here in FL, also see how well they hold up with all the opening and closing of the doors. Also easy to remove if I decide I don’t like them

Nice! Did they feel a bit loose when going in? I did have the thought that with the opening and closing of the doors they might come loose but mine went in pretty tight so I hope that won't happen. Based on my fit I don't think I could go any tighter, I actually pushed the center pin through the cap on one of them because of the combination of the very thin surface and it being too tight - I actually added a bit more surface on the inside to try to avoid that happening again.

I printed the black and gold one in PLA since I only have gold PLA. It's only been in there a couple of days (granted, 100+ degree Texas days and I park in the open) and so far it's doing ok. I don't expect that to last but only time will tell.

Thanks for the photo, that's the same as how they look in my XLT without the caps.

XLT with the BAP?

I printed them 6 up a couple of them seemed like they wouldn’t go in the hex opening just tried another and then they wouldn’t work, they seemed fairly tight, didn’t have any petg so used the pla will see how they hold up in the central fl heat
