KaThanha Mags v3.0

thingiverse

Here is the text rewritten in American English: This is version 3 of a tool-less, glue-less, screwless, half-dart mag based on the Katana platform. It utilizes a constant-tension coil spring provided by Foamblast. The mag is also compatible with any traditional half dart magazine box spring, as long as you glue in the base. To assemble this mag, you'll need the following parts: * 2x KaThanha Body * 1x KaThanha Thanhlon Follower * 1x KaThanha Sleeve * 1x FoamBlast Drum Spring This mag supports a variety of features, including: * "Knurling": This type of pseudo knurling/guide-rail pattern on the inside walls helps smoothen feeding. It's designed to reduce friction by changing the grain orientation on the surface that makes contact with the darts into being parallel with the movement of the darts. * Antisheering Dovetails: Locking tabs now feature friction fitting concave and convex grooves along the sides to help lock in the dove tails and protect against sheering motion. * Second mag catch slot: There is a secondary lower mag slot that's in-line with Hasbro's mag release position. It's intended for when you can shorten your blaster and ditch the adapter. * Jungling: You can stick the mags end-to-end and "jungle" them through the ExtensionSleeve. * Membrane Window: Initial few layers on the central channel creates preview window, utilizing the translucency of fully fused bottom layers. Put at least two layers criss-crossing diagonally for the best rigidity and transparency. * Vase Mode: Using the Spiralize Outer Controur option or "vase mode", you can slice the included sleeve files labeled vasemode (OPTIONAL) in order to get super clean low profile vases. If you encounter any issues with assembly, here are some troubleshooting tips: * If sleeve too tight: + Check if sagging, rough detents, or bulged; this will wear over use. Or, the mag is too wide, and your Z is different than the file. + Insert one half of a body into a sleeve to check if it's a z tolerance or a xy tolerance * Expanded capacity jams: + Manually inspect inside wall of the mag to make sure there are no burs (especially the interface edge where mag bodies contact each other), the path of the follower's nub should be smooth and uninterrupted. + Sandpaper is your friend, do a quick wipe to make sure the inner walls isn't grainy * Dovetails Too Loose: + If the dovetails are too loose, you can use a lighter to warp the ends downward so they contact * Bottom base sleeve too loose: + Boil the base sleeve for 10 seconds; your print will contract by a few microns in the xy * Fitting spring in: + Sometimes drum springs will be concave outward and the sharp edge will catch against the walls, resulting in difficulty fitting them into the spring rest. + You can easily just crease the tab inward so it doesn't catch against the back wall + In case the spring rest sags too much during the bridging, such that you can't insert the tab of the spring through; just gently melt that bridge with a lighter and press it up with a toothpick * Too tight for adapter: + Printed adapters will often vary with dimension because they're tighter and shrink more. + To compensate, you can shrink one half by as much as <2% Z (or onelayer) and they'll still click together, and gravity drop better.
