This allows you to mount your guitar to the wall.
It prints in two parts without any support.
The piece on the left (3rd Picture) gets screwed to the wall - the download includes a template to drill the holes. I use 5mm x 60 mm countersunk screws, the template also has 5mm holes, it's perfectly fine to just drill through the template, if you need to use a bigger drill.
The second parts slots into the one on the wall using a dovetail and as a bonus, it also covers up the screw heads.
Additionally, i added 1mm self-adhesive fleece to the inside where the guitar will hang (last picture).
Print as shown in the third picture.
