Kossel Mini Magball Effector with PCB Mount

thingiverse

This Kossel Mini effector is a revised take on Lauman’s Super simple upgraded Kossel Mini effector, combined with key body changes from RandomFactoid’s remix, along with a modification to the top collar to hold Think3DPrint3D wiring harness PCB. I'm using magballs and rods from Haydn Huntley: http://www.magballarms.com I’m only sharing the STL for the modified piece, and directing you to the two upstream projects for the rest of the components. The assembly instructions provided by Lauman are excellent. I created a more detailed Bill of Materials (BOM) for the required hardware: Hardware BOM: Magballs: (6) Magball nuts 3mm: (6) Cooling vent bolts (8mmx3mm): (3) ((4) if not using dc42 IR probe) Fan attachments (10mmx3mm): (12 - but I only used 2 per fan for a total of 6) Attaching collar to body (8mmx3mm): (3) Collar attachments (10mmx3mm): (2) Collar attachment nuts (3mm): (2) dc42 IR board attachment (2.5mm self-tapping): (2) dc42/T3P3 PCB attachment (2.5mm self-tapping): (2) Totals: 10x3mm: (14) (if populating all 3 fans with 4 bolts, otherwise (8)) 8x3mm: (7) (if using dc42 IR probe, otherwise (6)) 3mm nuts: (8) (if using Haydn magball studs, otherwise (2)) 2.5mm self-tapping screws: (4) (if using T3P3 PCB, otherwise (2)) The magnets in Haydn's rods are strong enough to keep fan blades from spinning, or even stop them after they start spinning. Flipping the rods can help. I am also investigating shielding for the rod-ends.
