The original Platypus design by RedCowl was a fantastically simple mod.
However, I found a lot of issues with some of the models. In the process of fixing the models, I decided to go ahead and just revamp the entire project with more QoL/aesthetic changes I wanted.

Thus, the Platypus Rex was born.

List of changes include:
-Fixes to the magnet holder sizes (many were too small to fit the magnets)
-Altering the latch hammer for easier access
-Optimizing/spicing up the main body
-QoL improvements on the barrel (including more reliable tilting and slots for easier shell-extraction)
-A new barrel design with faux muzzle-break
-Optional clip-on shell holders for each side of the blaster (holds up to 4)
-Optional iron sights attached to the latch and to the barrel
-And a few more minor adjustments to the models for model cleanliness/easier printing

Note: The Barrel/Shell Clips for this mod will ONLY work with Flypoint shells. This isn't made for the Cpt Slug shells.

Printing:
The pins (you will need 8 for all accessories) should be printed at 0.07-0.1mm.

Everything else can be 0.1-0.2 for best results. Some models will need supports, and I leave it to your best judgement as to orientation. (Most should be obvious)
I kept infills between 30-50%.
