Used a paintbrush and painted the recesses with white acrylic paint, then went over the top surface with black paint. Looks a bit more &#8220;together&#8221; but hard to keep it neat, and doesn&#8217;t work too well when there are fine letters on one key.<\/div>\n<div><\/div>\n<div><\/div>\n<div>Will settle for these until I can think of a better way to do them.<\/div>\n<div><\/div>\n<div><b>Update<\/b><\/div>\n<div><\/div>\n<div>The buttons are now made from white filament. On top of which are glued the letters that have been laser-printed printed on transparency sheets, with the letters in clear\/white and a black background. The higher resolution of the laser-printer makes the smaller letters appear clearly. The edges and sides are then finished off with black acrylic paint so we don&#8217;t see the edges of the transparency.<\/div>\n<div><\/div>\n<div>I left the digits and letters with the earlier painted version &#8230; the letters on the letters are big and therefore are bright and clear, and I can&#8217;t cut perfect circles in the transparency sheet for the digits.<\/div>\n<div><\/div>\n<div>For the EXEC key I made the button out of transparent PETG, in the hope that the LEDs below will shine through. That didn&#8217;t work too well, as the light isn&#8217;t bright enough. So I drilled a hole and extended one of the LEDs to the surface.<\/div>\n<div><\/div>\n<div><\/div>\n<div><\/div>\n<p><img decoding=\"async\" src=\"https:\/\/blog.shahada.abubakar.net\/wp-content\/uploads\/2017\/05\/20170531_170036-scaled.jpg\" width=\"100%\" \/><\/p>\n<p><i>Originally created with EverNote at 20170530T101818Z<\/i><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Struggling with my ABCs &#8230; who knew keypads could be so complicated?
