Ultimaker 5.5mm Wrenches

thingiverse

I design and manufacture my own custom wrenches for working with M3 nuts that have a 5.5mm hex head on my Ultimaker Original Plus printer. Unfortunately, most socket or wrench sets available in the US do not include a 5.5mm size, making it difficult to use standard tools in tight spaces. To address this issue, I created these custom wrenches to provide an easy and convenient solution for working with small parts on my printer. If the wrenches don't fit snugly onto the nuts, simply adjust your slicer settings to scale up or down a few percent as needed in the X and Y directions. This will ensure a secure fit without compromising the overall performance of the tool. These custom wrenches were designed using SolidWorks, a popular computer-aided design (CAD) software.
