Upgraded Pump for Orion Blasters Lynx

This model is a drop-in replacement for the stock pump grip for the Lynx by Orion Blasters and requires no additional hardware. The tolerances between the aluminum bars and plastic are improved which leads to much less side-to-side movement of the front grip when handling and priming the blaster. To make up for the increase in friction due to these higher tolerances, I have greatly reduced the contact area between the plastic and aluminum bars by making only small protrusions touch the bars. This leads to a much smoother and lighter prime. For an even smoother prime, you can add a tiny amount of grease such as SuperLube's multi-purpose synthetic grease to each of the 26 protrusions. (This is the same grease I use for my plunger tube. I have fired roughly 200 shots since last lubricating and haven't had to re-lube either the bars or the plunger tube yet. This grease is also very easy to clean and waterproof.)

I used some dimensions from the original pump to model this. For the overall shape, I took inspiration from EnderSavesTheDay's cut-down pump meant for his shrouds as I feel the geometric shape looks better than the original rounded shape. This model, however, is NOT compatible with the EnderSavesTheDay shrouds as the tolerances are too small. 

For printing, I recommend a 0.2mm layer height, 35% infill, and 4 outer perimeters for strength. Additionally, I have found the best way to support this model is to add support under the picatinny using tree supports. No other support is needed as the circle (which I plan to add a magnet to for retention) and the hexagons where the standoffs are sunk into don't need any support.
