HO Scale DC Motor Isolation Mounts

thingiverse

These are basic DC motor isolation mounts for use in Athearn Blue Box locomotives or other similar open frame chassis. I designed these around 15mm x 34mm can motors found on eBay. They are similar in dimension to old Sagami or Mishumi can motors. You should be able to stretch or shirnk to fit length. Be mindful of the radius if you modify the width. The short piece is for the bottom of the motor and should overhang past the leads, if possible, to fully insulate the motor from the chassis. The longer piece is for the top. Drill holes as appropriate for your loco wiring and run the wires through the top to keep things clear of your worm gear. The platform should be sufficiently long to mount a DCC decoder and sugar cube speaker. Both pieces are intended to be affixed with 3M double sided tape. I wouldn't recommend the foamy stuff as it is likely too tall and doesn't adhere well over time.
