Worker Seagull Bearing Priming Block

This priming block is a drop in replacement for the stock one on the worker Seagull. I was able to 

It uses:
8x 623 POM bearings (the same ones that Alchemist and my Unicorn block use) 

8x M3x10mm SHCS

This does require support. Orient the model such that the picatinny does not require support, and add support touching the build plate. I use the “snug” version of supports, but the regular one should be fine. Print this fairly solid, as it will be seeing quite a bit of force :D

For assembly. Use the SHCS to bolt through the bearings. The bolts thread into the plastic, and the heads are tight, this is to ensure they DONT come out while using the blaster. The bar retention bolts (the 4 countersink ones that you took out of the original priming block) are reused to bolt into those bars. 

This should be compatible with the return spring, but if you find issues with that working, please let me know. I believe there are inconsistencies with the return spring for the seagulls and would like to know more. It did work with my return spring, however I chose to remove it, as it was a nicer feel overall. I recommend you do the same

Edit: this should also work with the harrier WITHOUT the return spring, as the blocks are the same, but the springs are not.
