Version 2
After selling quite a few of these I've made a few improvements and updated the model based on customer feedback and testing:
-Increased thickness and added support
-Larger hole to better fit battery terminals
-Cool grip style decal edging
Details:
Adaptor for mounting the M4A1 Buffer Tube onto the Scar V2 Gel Ball Blaster Toy Gun. For best results print upright with supports. The means the connecting tube will be printed horizontally, making it a stronger print. A layer height of 0.18 or less is fine. ABS, Nylon, and even HIPS filament works well.
This part + some of my other designs are available already printed in high quality ABS Max filament. These can be purchased via ebay at https://www.ebay.com.au/usr/harleyshg
Enjoy!
