magnetic gun stock for valve index controllers by kevinm88

Last crawled date: 3 years, 1 month ago

this gun stock uses a magnetic break system to separate the two parts, unlike other systems the stock can not fall to the side and you only have to join two parts back together rather than the standard 3. the recommended magnets are so strong you only need to bring them with in 5cm of each other and they will line up and join them selves, the index tracking system doesn't like shocks so you will have to practice so you can control the reattaching of the two sides.
the stock should come out at 150grams of pla, some rather large magnets and almost no weight of carbon arrow shafts.
fortunately given the parts are welded together you can resize any part other than the two controller holder pats without much consequence. ***
some of the parts require support, if your printer has issues with bed adhesion a tip is to sink a part into the bed by .2-.6mm in the slicer program, giving a larger first layer.
the parts are glued together with a 3d pen capable of 200c, then the front arrow shafts are attached with m3 screws and the rear ones are attached with superglue. the rear of the stock pivot points use m3 screws, then the pivots are locked in with the 3d pen (once you can determined comfortable angles. the shoulder pad is covered with a cut of sponge then covered with silicone tape or tennis wrap. then the tips of screws and sharp edges that the 3d pen leaves are covered with duct tape, silicone tape or tennis wrap.

*get the cheapest pen of ebay they should be around 12-18 USD! don't get ripped off with a expensive brand one that will preform worse. 3d pens produce a weld that can be stronger than the part you are welding.
**ideally you can buy a single arrow or be given a broken arrow from a club or archery range. most archers seem to have a collection of broken arrows. higher spine arrows maybe too bendy. you can in theory use wooden dowels or other thin round stems. ***
