SG90 Servomount (with linear guiding)

by pauldistel

This servomount consists of part 1 in four different versions which can be fixed with screws. Part 1 can be printed without extra guiding or with guiding on either or both sides. Use a small size paperclip to create the wire for movement through the guiding. The SG90 servo can be installed with part 2 which can be fixed with two countersunk M3 screws. The normal size servo arms cannot rotate the full 180 degrees. This mount is for small horizontal movements, for example for turn outs in modelrailroading. This mount was specifically designed for Märklin K-rail turn outs. Updated version 1: no support needed. Updated version 2 (2025-11-23): 0.5mm added in length for better fitting of SG90 servo's.
