Perfect item! After some failures I contacted the author which has been super kind and got me some possible solutions, finally I've got this printed.
My problem was, the nozzle was hurting the smaller towers where you can see in the picture, happened 7 times, I tried everything: slow down, rotating, supports, etc.
This evening it simply did.
nice simple design. I wanted to load my ams for an overnight and realized one spool I planned on using was a 500g one. so I printed this off quickly and it's having no problem rolling sr
The adapter printed will, but it seemed to have some gaps and mess up on my printer. it was a new roll, so it couldn’t had some humidity issue or something like that.
