Laser holder for d=12mm laser module for BQ Ciclop

I'm trying to build CICLOP scanner developed by BQ.
And... After printing all the pieces and buy lasers I discovered that the holders that come with the original pieces set not serve me because my lasers have a diameter of 12mm.
After attempting to modify the original piece without luck I drawed it in 3d from the beginning. There you have it.
