MaH - Modular Arm Helper - No support - Easy print

thingiverse

## MaH - Modular Arm Helper MaH was brought into existence because I desperately needed it at my desk. So many times when I'm busy doing things and need to hold more than two things, like a soldering iron, tin, wires, or components. This arm helper really helps me get stuff done more easily. There are a few things I had in mind when designing this: - **No supports needed when printing any component (this was REALLY TOUGH!)** - **Strong and stable**, the arms at 40% infill are very strong. - **Easily mounted and moveable** (print two bases, move the arm, there you go!) - **Modular**, if I ever need a new component I can just create one, and hopefully you will too! ## PLEASE READ PRINT INSTRUCTIONS BEFORE PRINTING! This print needs some horizontal size compensation or the parts won't fit. In Simplify3D, it's in the print settings under the "Other" tab in the bottom left corner. Enter a negative value of minus 0.1mm. So you enter "-0.1" without quotes. #### Update 17-04-2018 - Added a new and stronger gripper (mah_gripper_v2_* files). I suggest you print this instead of the V1. Print with 60% infill, two perimeters, no supports (yay) and -0.06mm horizontal correction. #### Update 14-04-2018 - Added a clamp mount option. Now you can pick a fixed screw mount, rotating base mount, or a clamp mount for your arm. Take it anywhere! On your desk, on the wall, whatever you need. ### Rotational or Fixed Base If you don't want a rotational base, print the mah_base_fixed part instead of the core+shell+base_link. *You can mount these bases on the wall, or any surface you can screw into. Or make your own clamp version! Go nuts.* ### Components There are a few components: - The base shell - The base core - The base set screw - The base male link - The arm - The arm screw - The gripper And some other peripherals. If you print everything at 40% infill, it will be very strong. There are however some tricks I applied to make it even more durable so be sure to read up on the print settings. ### Printing Tips I printed EVERYTHING with a minus 0.1mm horizontal compensation. Makes for a very tight fit. Also check out the layout on my printbed so you know in what orientation to print said things. ### Questions Please let me know if you have any questions, have fun with this! I will try to upload every source file so you can continue working on this.
