3D Printing

Left Hand adapter to play piano without a full hand

I stumbled upon this wonderful 3D design which is actually printable.

It is an attachment to be clamped on the arm so you can play the piano.
It allows you to arpeggio one octave in the major and minor scales on all of the white and black keys!

A wonderful design if you’d ask me. I think a lot of people would like to have solutions like this.

Now, in case you are not able to print it your self. You can order prints on Thingyverse or if you live close near me (The Netherlands) I can print it for you for just the material and shipping cost.

Be sure to visit Mat Bowtell his Thingiverse page.

You can find the design and the arm attachment design in the links below.

PSU replacing Frame brace for Original Prusa i3 MK3, honeycomb

Download STL files here.

To keep the strength and use less plastic I changed the fill to honeycomb and added two bars near the edges to prevent bending.

Made this as part of my LACK modification for “Original Prusa i3 MK3 ENCLOSURE -Ikea Lack table – Prusa Research”
