Simple wall mounting bracket for storing Chinese 250-000 series lathe toolholders (such as https://www.arceurotrade.co.uk/Catalogue/Machines-Accessories/Lathe-Accessories/Tool-Posts/Model-000-Quick-Change-Tool-Post-Set ) I believe these are the same size as the Aloris MXA series, so it should work with those too.
The bracket is deliberately a loose fit on the toolholder so you don't have to fight the tools on and off, and to make sure an errant chip won't jam everything up!
Edit: I was contacted by another user who found the fit on the Aloris MXA to be too loose. you can find their remixed version here: https://www.printables.com/model/406634-aloris-mxa-t-slot-cleat
Works fine in PLA with fairly low infill, although you might want to locally increase the infill percentage around the screw holes with a modifier if you're going to use power tools to install the bracket!
