Here is my first 3D model so be gentle.

I remixed the Aldi Xfinity battery connector by @Stoney with the Makita side of the Makita to Festool Battery adapter 18VLI 5,2 to Makita 18v by @royag.

The battery form factor is shared by Aldi Xfinity, Bauer Hypermax by Harbor Freight, Baumr Ag, VARO tools and Ryobi one (Only the South African Version). The electrical connections may differ.

I set the Aldi battery to go in from the rear of the tools to make it easier to wire the thing.

I got fed up of paying over $100 for Makita batteries of the same capacity of the Xfinity ones that can be had for $40 seasonally.

This thing hasn't been printed or tested yet. So I can't really provide any printing settings.

I mixed this in Meshmixer. I had not used any 3d modelling software before.

Also. Sorry about the size of the files. I couldn't find a way to make them smaller. The thing has been uploaded in several versions and two different file formats.

I also uploaded another version with a little more offset to use it in the 36V makita blower. The air intake is located by the batteries and I was concerned it did not have enough clearance.

To install it in the blower you need to put the battery in the adaptor first and then put the pair of assembled batteries on the battery bay.

WARNING: DO NOT USE THIS ADAPTORS TO CHARGE THE XFINITY BATTERIES IN THE MAKITA CHARGER. USE AN ORIGINAL XFINITY CHARGER.

EDIT: I received my printed files. The one with the offset works perfect so I am deleting the other files but I will keep them in my computer of someone wants them.
