Description
These MLOK rail panels are intended to use infill to generate texture. Using the infill percentage, a finer grip or more aggressive grip can be achieved. Change the infill patterns and experiment with which pattern and density provides your preferred level of grip. At most, a single 3 slot panel uses 5-6 grams of filament so you can print several trial and error examples until you find the one you like.
Additionally since they are blank, if you're savvy enough to create a texture yourself you can do so knowing the more technical part is already figured out for you. The panels adhere very closely to the MLOK pattern - they will snap into place and stay there without the hardware even, though I wouldn't rely on that for any serious use.
There are two side profiles of cover available - the standard profile is chamfered nearly flat on all four sides to keep the panel snag free. These panels will work best on oddly shaped hand guards ( like the Krytac LMG pictured ) or for only placing panels on the sides and bottoms. For handguards with 45 degree mounting surfaces ( like the URX 4 replica pictured ) the relieved models have their chamfers cut opposite to allow them to be mounted right next to each other for full panel coverage around the handguard. Both models will line up next to each other in a straight line without issue - you can mix and match them depending on what coverage you want to create.
Lastly, the narrow model AFG-H ( https://www.printables.com/model/1379165-afg-h ) I designed will tuck in under the chamfer of adjacent relieved model panels, creating a wrap around cheese grater for your bare hand if you want.
Print settings - the important bit. Use 0 bottom layers, 3-5 top layers depedning on how deep you want the pattern, and face the panel with the MLOK bits facing up. If you used a textured bed sheet, it will also transfer a bit of texture from the sheet as well. I also recommend dropping your first layer speed considerably, depending on how well tuned your first layer adhesion is and the sheet/filament you're using, to below 20 mm/s. I like 10 mm/s myself, but I've also forgotten and had it print just fine at 20 mm/s.
The standard models pictured utilized 6 perimeters and 20-25% infill ( honestly I forget ) of the hilbert curve infill.
The relieved models I only used 2 perimeters and 20% hexagonal infill.
I designed the holes and chamfers for the hardware around this kit - https://www.amazon.com/dp/B0D1CPJWF6?ref=ppx_yo2ov_dt_b_fed_asin_title
Magpul genuine hardware will work but will stick out past the panel.
