This is a remix of “Multiboard Tool Holders” by Techjag. It solves the issue with the tool holder falling off of the Multiboard.

I changed the connector from the standard connector to the “moderate weight” connector.

I also added a 4 mm spacer between the Multiboard and the tool holder to allow for the handles on my pliers.

Print this with normal supports on bed only, 3 walls, and 15% infill of your choice. Matte PLA works well and should be stronger than standard PLA.
