Use double bubble machine size refills. You may need to clean out inside of base depending on how well your printer bridges. You may want to use supports though I am not sure how easy they would remove from inside.

UPDATE 12/6/18

I added spinner_v2(works with base v2). Because the large slope in v2 prevent the spinner from rotating. Thanks to shiblon from instructables https://www.instructables.com/member/shiblon/ for pointing the problem out as well as fixing it.
