GDR street lamp RSL 1 with octagonal mast profile (1/120 scale)

thingiverse

Street lamps of type RSL 1 were common in East Germany (GDR). For round mast shape the standard was TGL 20997-01 from 1973 [1] and catalogue B 7320 PEM [2]. I recognized the octagonal masts of my childhood and after some research in the TT-board (thank you Werner) [4] I finally found and built some of them with octagonal profile in TT (1/120)scale.The 2K Moxa Lighting GmbH still produces similar lights [3].PrintingUse the versions 05 or 04. The version 05 has small improvements, but I did this after I printed enough for the next time ... The version 03 has different connector between mast and head, but maybe you want to do try something differentgray/dark resin for the mast (I printed strait up to get a better shape)You need to wash out the resin from the hole before curing! I used a syringe with alcohol.clear resin for the lamp head (I printed head side down for easier cleaning process)LightingThe head has a place for a SMD LED size 0805. I soldered the LED between two 0.3mm enamelled copper wire in the direction of the light and glued the back of the LED into the head (see sketches).I used the version 04 parts for my final prints, some pictures may display my prototype version.Origin and licensingI don't want any commercial use of this design and prints. You may use parts and change them to your needs, but please keep it free and non-commercial.You are free to print my work for your projects, close friends and maybe your model railway club. Please post your makes.If you are representing a model or railway club, a school or something comparable with these and want to use it for educational purposes in higher numbers, please tell me.[1] TGL 20997-01 (1973): https://bauarchivddr.bbr-server.de/bauarchivddr/archiv/tglarchiv/tgl20001bis30000/tgl20501bis21000/tgl-20997-3-jun-1973.pdf[2] catalogue B 7320 PEM (1973): https://bauarchivddr.bbr-server.de/bauarchivddr/archiv/plarchiv/00141-c-2431/akten-und-mappen-pdf/00141-c-2431-katalog-b-7320-pem.pdf[3] Moxa Lighting: http://2k-leuchten.de/Serie_RSL_I[4] TT-board: https://www.tt-board.de/forum/threads/ddr-strassenlaterne-typ-rsl-1.48215/
