This is a handle for draws and cupboards which includes a pattern on the front generated by the Commodore 64 one-liner program 10PRINT. If you want to learn everything there is to know about 10PRINT I highly recommend this great book by Nick Montfort, Patsy Baudoin, John Bell, Ian Bogostm, Jeremy Douglass, Mark C. Marino, Michael Mateas, Casey Reas, Mark Sample, and Noah Vawter.

The handle has a 80mm hole spacing and the holes are intended to be used with M3 heat press metal inserts, however the STEP file is provided if you want to modify for your own purposes. I printed with a colour change after the 1mm mark to get the result seen in the images. The 3MF file included has this setup. I recommend the bridge at the next layer after 1mm go lengthwise for the best results.

I created the handle in Onshape using a custom FeatureScript which randomly generated the pattern to be subtracted from the geometry.
