Thumbs up 3D Printed Reservoir Mounts

Just installed a set of these bad boys from rapid3design.com. 3D printed mounts that hold my MCS reservoirs in place attached to the stock strut brace. Pretty slick and the first 3D printed part I've gotten on the car. Anyone else have anything 3D printed? Seems like the possibilities are endless.

I did a sound tube plug, and a brake reservoir cap cover. I think I have pix in another thread on here.

I might be late to this discussion but is the engine bay the only place with enough room for the front reservoirs? I thought the primary reason for reservoirs was increased thermal capacity to keep the oil from overheating.

Have you already installed this on your car? This part doesn't smell right to me.

The website doesn't say what polymer they're using to build the part, but judging from the flexibility shown in the video, it's likely thermoplastic polyurethane (TPU). They have you heat it up to (1) expand the diameter of the two holes, and (2) make the polymer more flexible, likely getting close to the glass transition temperature (Tg) of the polymer, making it much softer.

What concerns me is the underhood temperature possibly exceeding TPU's Tg of 65 C (150 F). I don't have any numbers on under-hood temps, but 150 F seems plausible on a hot summer day. Keep an eye on these and make sure they aren't deforming.

Yes, they are installed and being used.

I am not the first person to install and use these. They have been on multiple cars for testing with over a year of racing abuse, no issues reported.
