<h3>Isofix cover for BMW E46 </h3>


I was missing one of the isofix covers so I modeled and printed this one. It's not a perfect copy since I added a bit of thickness in some parts to make it stronger.
You can see in one of the images the differences between the original and the 3d printed part. For this one the ABS filament is required since the PETG & PLA are not rigid enough.

<h1>MT99 Multimeter battery mod</h1>

This is a back cover replacement for Mustool MT99 multimeter (the MT77 and MT99PRO models are similar).

I wasn't too happy about the battery life given by the two coin batteries so I've made a case for a battery mod. It houses a battery, power charger and voltage booster if needed.

The frame has space for any battery up to  47 mm X 47 mm x 8mm thickness, when using the covered version.
I've included a second model (edge), as a variant if you plan to use the original back cover. It has the advantage of about 13 mm thickness clearance for the battery.

You will need some supports for the Usb cable port, depending on the print position.

I've included some cylindrical geometry supports at the corners, those align with the back screws. It would be easier to drill the holes without hitting just the infill.

**_Alternative solution for BMW E46 Double Din AC Relocation Bezel._**

<p>After a  Double Din radio replacement you have to move the AC unit on the lower frame but the unit doesn't fit that well.
This is a simple solution that uses your original frame, the 3d printed part ("clamp") and a nut/bolt to fix everything in place. </p>

[Youtube video of the 3d clamp installation](https://www.youtube.com/watch?v=ETz905bmVaM)

The original frame is altered just a bit. On the left side it has a small lip that needs to be cut off, this helps with the AC panel alignment.(see image)
Before the final assembling you'll have to fully slide the clamp on the AC panel. Drill a hole through the original frame using the model hole as a template. Make sure the bolt and nut are locking with ease.

This solution doesn't require any new bezel or front lip.
