Cool idea 3D printing for paintball. I was planing on purchasing a 3d printer myself anyway before the current administration makes them illegal.
People would be more receptive to the hopper if it had a smaller profile. Think 100round Rotor with revi internals thats excepts a standard speed feed or get exalt to create a miniature version.
You have to look at it like this. Why would I go threw the trouble to print one or have one made by someone with a printer. Then purchase or pull apart a hopper I already own or had to purchase used or new. To make a 100 round hopper that has a larger profile then 200 round hoppers redly available and on the marker currently. I love the idea. I love the concept. The product design I feel is missing its mark.
If you make it people will buy this. I would be more then happy to pay $150 for it. Im sure others would to. R1 has no plans to produce this many and people have called asking them to. There are a lot of pump players that would love to have something like this. Pump is making a comeback in paintball. I have noticed it over the past few years. Look at the industries bigs making pump guns. Empire bringing back the Sniper, Bob longs MVP, CCMs waiting list, and kids crying for more then they can produce. Pump is an inexpensive way for people that cant afford $2000 events to stay active in paintball and it's growing.
