@ScottYoung_4912125 thanks! I signed up for maker world and reported the post.

@zuberio I compared the files side by side in the slicer and it is exactly the same.
He's brazenly taking credit and thanking people for their kind comments, which should be directed to you.

This is great!
Would it be possible to offer it in a STEP file fomat?
I would like to play around with the design.

@Hogo_2353670 Sorry, I designed this in Google Sketchup 8.

Super nice tool, printed easilly in PETG with some brims as recommended.

it was a bit difficult to remove the supports that were automatically generated since the slicer didn't allow for such large overhangs but it works pretty well with quite the strong grip for a chunk of PLA, pretty neat though

This came out great! I'm considering making a larger print of this using PETG. Has anybody had any luck with that?

Oh snap! This looks gorgeous 😍! I'm going to print out an army of these little critters.

Printed in PETG. Have used for soldering header pins for tiny boards. (edited)
