Obsolete - Katobu Side v5 Catch+Spring Mod

OBSOLETE - My changes to this model have been incorporated into the mainline Katobu model. There is no need to print this - use the most recent version of the Katobu magazine instead.
This is the sidewall component of Tobu's Katobu short-dart Nerf magazine, which I've modified by adding:
- A slot in the sidewall to contain the free end of a drum spring
- An extra lower retaining catch slot, for compatibility with some adapters that use the blaster shell's catch
This part is identical to the part 'katana_side_v5.stl' of the source Thing, Katobu Mag. Simply make the Katobu as usual, but substitute this part for katana_side_v5.
If Tobu updates his/her design, this part may no longer be compatible. Use with caution!
