This is a Honeycomb Storage Wall compatible holder for Dymo labelers. The specific model I made it for was the LabelManager 160 but any similarly shaped label printer ought to fit. Made to use minimal plastic and allow for quick grabbing and hanging.
You will want to print it with the arms on the bed and support enabled, this will make the curve of the arms come out nicer and is necessary for the HSW connectors.
The author remixed this model.
Used the original mounting file and dimensions with custom additions.
