模块化铰接台灯

A clamp-on desk lamp which uses an E14 / SES / Small Edison Screw lamp holder with a typical M10 threaded connection as is used in a lot of table lamps. Lots available on ebay. I got mine, complete with cable, switch and plug from an old lamp in a charity shop (thrift store)
Desk mount will cope with most desk surfaces up to 40mm thick.
The printed example uses:
2x 200mm arms
2x 300mm arms
1x shade
1x lamp holder
4x cable clip
5x knob
1x joiner
1x 90 joiner
1x desk mount
1x desk mount bolt
1x m10 connection piece (if not included with the lamp holder)
Non-printed parts are:
5x M5x30mm hex head machine screw/bolt
5x M5 nut
1x m10 nut (if not included with the lamp holder)
other arm lengths included to suit your circumstances.
Each arm has a side for hex bolt head and a graduated side for clamping. Pai should be used in the same orientation (one side with the hex hole pointing out, one wise with the graduated clamp side facing out) - not facing each other.
