PS-3 Profile Spacers
Stop crushing your TPU. Lock in your tune.
Designed to solve the common issue of over-compressed 3D prints. PS-3 spacers create a rigid, metal-on-carbon contact point, allowing you to torque your screws fully without deforming soft TPU parts.
Key Features
- Zero Deformity: Protects TPU from being crushed, keeping your build clean and durable.
- Max Rigidity: Allows for full screw tightness for a "bomb-proof" mechanical bond.
- Cleaner Audio/Gyro: Eliminates micro-vibrations caused by loose soft mounts for a smoother flight.
- Premium Material: Precision CNC-machined from aerospace-grade 7075 Aluminum.

Excellent brad excellent hardware as always
The only problem is there are only 15 in a pack....it takes qty 16 to mount 4 motors on most drones depending on the tpu design...wish i could just get 1 pack of 16
ALways use Quadmula 12.9 hardware on all my builds! Even if they arent always Quadmula frames. They always use the best parts!
Love these frames and the profile spacers should be industry standard!
The Best Choice for Strong TPU Part Connections.
They are perfect
Iykyk get them!!!
Experience was good. Probably could save us all a little money if you put those $6 glorified washers in a plastic bag.
Love the quadmula frame and design , and the spacer system is an incredible touch. Utilizing them on a custom GoPro 11 mini mount. Couldn’t be more secure. Best frame around.
Amazing option to mount your GoPro 😎 https://www.thingiverse.com/thing:5847263 https://youtube.com/@denisedobb406?si=EnSIkaIECMiOmarE Thanks Quadmula
No more pulling the screw through the TPU print, Simple yet ingenious 👌🏻
excellent parts
Great option for securing tpu prints
Came quick and exact!!!!
Love these spacers! Only problem is that I need more already lol
Well made
These should be standard in all frame designs! My only gripe is quantity, offer a 20 pack.
they work great so i bought extra for other tpu mounts
Great spares!!!
Great spares!!!
Really great Idea. It lets you wrench the screws down tight.
I love these things! The only thing I would prefer is if they were steel or harder aluminum because they take damage from the ground pretty quicly. I'll always keep extras on hand! Can't have a Quadmula frame without em!
