 Product Description

This is the original uni-spacer designed by Robert Wheeler (pLaStIcsPiDeR ). A portion of the sales of this item go to him, the designer! You get the same quality from Great3d on this amazing spacer as the rest of our other products with the added benefit of helping the designers that give us these great products we use!. Check out his new vent additions or LED holes to add an even more custom look and provide air-flow to your ESCs! Warning: The vented option decreases the strength of the uni-spacer. We do not see this as being an issue due to the non structural role the uni-spacer plays. Overall we see the added benefit of the decreased weight and airflow an added bonus for the uni-spacer!       These are not compatible with the Version 2 frame sold from MRM.

Note on Arm Thickness.  The stock ZMR250 frame comes with 3mm arms.  The stock FPV Model ZMR250 V2 Frame comes with 4mm arms.  Be sure to choose the correct arm thickness when ordering. 

The 16, M3x18mm screws required are not included but, can be added to your cart here: (you will need 2 packs)


Nucleus Option

Uni-Spacer with 45 Degree Vents. Re-designed for the Nucleus PDB. The front and back has been moved back 2.5mm to clear the onboard LED's and there are 2 notches in the front to allow clearance of R2 & R2 Resistors. 

LED Option

LED Hole spacing is for WS2812B 5050 RGB LED Strip (60 LED's per meter)
Has holes for 10 LED's (2 Front, 2 Rear and 3 each side)
Here is a great video by ModifiedRC did on how to program RGB LEDs on cleanflight

  1. good but..

    Posted by Unknown on Feb 17th 2016

    Holes were too small for 3mm hardware, had to bore out every one to make it fit. Make the holes 3.5-4mm and I would have no complaints.

  2. BUY IT!!!!

    If you're building a ZMR250 this is a must have it will allow you to mount the ESCs between the bottom and middle plate instead of on the arms making for a super clean build. Just make sure you get it in TPU it will literally beindestructible.

  3. Love this spacer!

    This unispacer is one of many great products the great3d.com prints. It really helps clean your zmr 250 build up AND it looks cool!

  4. great fit

    Posted by Yan Chabot on Oct 26th 2015

    i bought this not knowing if it would fit my pdb, sure enough, it did. that's because my pub is the overcraft V4, witch is pretty close to the fpvmodel one... (i suspect them to have stolen the layout from it), i have to say i am glad i did not print that part myself, i say leave it to the pros!

    i have to give credit to Kenny that thing is a work of art, i have the red one made out of TPU it is translucent the vents on it are perfect! i wish i could post pictures of it, now i am afraid to take my quad for a spin, it is soon pretty now!

    thanks Kenny

  5. Fits Well

    Posted by Douglas R on Oct 13th 2015

    If you order this for a V2 frame (with 4mm arms and 2mm plates) you'll want 20mm bolts for the arms and front/back stand offs. Otherwise this still works and it works well. Happy with the print and fit.

  8. Nice and sturdy, thin frame

    Posted by Dylan P. on Aug 21st 2015

    The arm mounts are very thick, overall it's a lot more sturdy than it appears!
