This requires ABS/ASA .  PLA or PETG will fail  This is thin enough, that it should print on any printer.

This is my take on the Stealthburner LGX Lite PCB mount.  It may look flimsy, but since it is held in tension it isn't.  I have one with over 500 hours of printing, no issues.  It will also work with the LDO Nighthawk, and other toolhead PCBs as well.   Uses ultra low profile screws to mount to the LGX.  https://www.amazon.com/gp/product/B0C5M9RLW8/ref=ox_sc_saved_title_3?smid=A5E984U90G1AK&th=1

Use a couple of pieces of kapton tape to cover the screws use to mount to the LGX.  The screws mounting the PCB to the mount also need to be fairly short, or use spacers.  Also it may be required to trim the long solder joints on the underside of your PCB. 

I do also use the Linneo LGX Lite Fan PCB that kb-3d.com sells.  

I have also upload a couple of modded mounts that bondtech had developed.  The front mount is cut for the 3DO camera, and the rear mount is cut for the LGX Lite V1 or V2.  I have not had a LGX lite PRO, so I do not know about those.  Also Included is a bondtech Stealthburner body that has a couple of notches to assist fan board fit.  Also recommended is the bondtech PCB cover, because It has more room. You can find it on Bondtech's github.  https://github.com/BondtechAB/Voron/blob/main/Voron_2.4-VT-SW/LGX_lite/STL/LGX_lite-CW2-SB/10100-06_StealthBurner_PCB_Cover-FDM.stl
