Ego 56-volt ST1500 trimmer bump head (AH1500/AH1501)

Ego 56-volt ST1500 trimmer bump head (Part No. for replacement head is AH1500). For the STA1500 Multi-Tool trimmer attachment, the bump head is: AH1501.

Why? Made this because I wore out two of them, and at $30 each, they are cost prohibitive. Other people have complained about the same issue (soft plastic, and thin design.

Note: the AH1501 looks very similar, but the tab on the inside is off-set by 60 degrees, and the rotation is the opposite direction. Bottom line, will not work. Once I get this design finalized I will make a bump head for the AH1501 too.

Update 3 (10/13/19): AH1500 and AH1501 both updated to v105, to correct the inside hole being too tight (increased diameter 0.010"). Note: v104 will work, but you have to insert the Ego nut, and spin it with a drill to create sufficient clearance.

Update 2 (10/10): AH1501 v104 uploaded. Known issues: The center hole may need to be reamed out; if so, I'll create an update STL.

Update 1 (10/09): Completed the minor change to the AH1501, v104 is the latest. Testing the AH1501 print, and will upload the STL tomorrow.
