Housing for replacement pancake type motor to suit old Hornby/Lima ringfield motors. Suits COCO or BOBO bogie sets. Two different designs as I found there was a difference due to age of the units. Print flat with no supports. I print in PETG because that's what I prefer but PLA should be fine. Designed in Tinkercad. Motor should be a press fit. Motor OD 24.2mm 9.3mm High 12V. I got them on Alibaba https://starchinamotor.en.alibaba.com/ for $2USD per piece plus shipping. Best upgrade for old locos you can do.
