V4 body added addtional wire path. Increased the rear screw clearance. And made the locating tabs 6mm.
Added a 5mm pin for using a 5mm steel pin.
Added a 4mm threaded pin for use with a 4 mm carriage bolt or hexbolt. Printed the one I tested at .15 layer height. should be fine at .2.
You can use a sex bolt with the unklicky z. you need a 4 mm threaded rod or cut the head off of a 4mm screw and use that as a post into the 4mm threaded pin.
I have added some generic pins. To the cad that are intended to be building platforms. If you have a good Idea for a pin let's see it @@
Moved the bottom magnet inside the body to allow it to be closer to provide more lift. Changed the contact to not require a wire wrap. Now the heatset will contact to the contact screw directly. Wire is securured under the screw now to make a cleaner method of securing. There is a slot to stop the heatset you will feel it bump when it is deep enough. The new magnet locations have increased the spring to around a 245 grams of lifiting force. (this is using my finger and a scale take with a grain of salt) But this is about 150% increase from the v1.
There has been a script created to test the noozle ooze that can be used for any probes and endstops. But do want to thank Jkwang for a great new tool. You can grab it from his github at https://github.com/johnnykwwang/3dp_notes/tree/main/auto_z_accuracy_test.
