Dual voltmeter holder

I needed a mount to hold 2 pcs https://www.banggood.com/0_28-Inch-2_5V-30V-Mini-Digital-Voltmeter-p-974258.html on a aluminium 3030 profile for 6mm nuts, to monitor 2 voltages (24v for the motors and 10-12V for inductive probes and fans), it needs some smooth pressure to get the voltmeters into the holder, but that makes it work without screws.

I printed mine with PC/PCABS, without any scaling, but as there is no load on these parts every filament will be fine.
