This is a replacement for all new BuzzBeeoid type blaster catch hooks, in case yours breaks. The BuzzBee catch hook design is thin and prone to snapping under unreinforced high springloads.
Simply snip off the appropriate amount and epoxy this on. I recommend you print this in petg, abs, or pla+ for strength. Tested for up to 12kg. There are some variations within the rod guide for which the plunger rod slides in, so you may have to do some sanding on the top and bottom sides to fit accordingly.
