I designed this convenient under-desk hanger for my Flea Ukulele, below my Uplift adjustable desk. The Uplift desk frame has many extra holes available so I decided to take advantage of them to store things somewhat out of sight. Check my other models for a headphone holder of a similar design approach. The Flea uke has a unique headstock design with a hole that made a simple softened hook a straightforward and clean design.

Print this model with the base on the print bed (see photo for reference). It looks like a big overhang but prints fine without supports. I printed in Prusament Galaxy Black PLA at 0.2mm but you can experiment with variable layer height if you are concerned about smoothing out the surfaces. The included GCode file is set to a relatively high infill to provide good support for the attaching bolts. Two M8 x 15mm bolts are required for attachment, easily found at any hardware or big-box store if you don't have spares from your desk assembly.

Mine is a Flea Koa Concert size and does not touch the ground at the lowest setting on my Uplift desk. PLEASE CHECK YOURS and ensure that your minimum height limit setting will not damage your uke.
