ABS seems like it would have about the right springiness and toughness, and with acetone polishing one can achieve a pretty good surface finish. I believe that natural white color is available, and if thin enough the light should shine through just as it did on the original.Markhttps://www.blogger.com/profile/10200230310372007729noreply@blogger.comtag:blogger.com,1999:blog-1290923408109546049.post-33754422413534085162020-06-21T13:40:05.096-04:002020-06-21T13:40:05.096-04:00Not so far.

It is well away from the generating area, and is made of MDF, a conductor. Any spark capable of jumping to it should penetrate a paint film easily. furthermore, while operating, your hand (a good conductor)is closer to the high- voltage areas than the base.<br />Tony Webbhttps://www.blogger.com/profile/14140048111616463480noreply@blogger.comtag:blogger.com,1999:blog-1290923408109546049.post-41574083170725591052018-02-01T14:50:36.049-05:002018-02-01T14:50:36.049-05:00No spam, please.No spam, please.The Mac Doktorhttps://www.blogger.com/profile/08235572436888747948noreply@blogger.comtag:blogger.com,1999:blog-1290923408109546049.post-67593191625247631972018-01-31T23:22:51.350-05:002018-01-31T23:22:51.350-05:00This comment has been removed by a blog administrator.Anonymoushttps://www.blogger.com/profile/04787023263001321201noreply@blogger.comtag:blogger.com,1999:blog-1290923408109546049.post-78675794270270994092018-01-31T21:47:21.806-05:002018-01-31T21:47:21.806-05:00This comment has been removed by the author.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1290923408109546049.post-4014338919470310972018-01-30T12:02:55.255-05:002018-01-30T12:02:55.255-05:00No spam please.No spam please.The Mac Doktorhttps://www.blogger.com/profile/08235572436888747948noreply@blogger.comtag:blogger.com,1999:blog-1290923408109546049.post-29540716931920307602018-01-30T11:21:34.480-05:002018-01-30T11:21:34.480-05:00This comment has been removed by a blog administrator.Naha Malikhttps://www.blogger.com/profile/03270932340126910592noreply@blogger.comtag:blogger.com,1999:blog-1290923408109546049.post-24733250425445293692018-01-16T14:48:22.242-05:002018-01-16T14:48:22.242-05:00Thank you.
