bsa meteor mk5 mainspring compression tool

Bsa meteor mk5 mainspring compression tool I use it with a Silverline 613111 sash clamp

Must be printed at 100% infill in the upright position. 

0.20mm layer height

I use pla for it without any problems

Please note that you can be seriously injured  if you don't know what you are doing by removing or installing  a mainspring. I I have used this tool for quite a while now with no problems but don't accept any responsibility for any damage or injury caused buy using it.

**It has been brought to my attention that my design has been stolen and is being sold on a auction site. I don't mind people printing and selling my designs but it would  have been nice if I were asked if it was ok.  The model  was ordinally posted with no commercial use but it looks like that means nothing**
