Makita 7,2V to 2S LiPo conversion mod

thingiverse

I find this old Makita 6018D without battery. I think i want to use it but the aftermarket NiMh battery cost too much. I just figured out how can i use my old drill with LiPo battery which is cheap and durable. Layer height: 0,2mm I printed it on my Anet A8. The top and bottom part fit tight so i don't need any adhesive to fix it.
