Spirographic WDT tool

Remix of the Bearing based spirographic WDT by Kensei @Kensei_237841. Also used some modifications made by @ungodly and @Kampflafer, so it has no handles and has fixed positions for the external needle.

I have splitted the lower body in two, and made it threaded so that it prints with no supports. With this I removed the sloped part and made it a little bit shorter.

It also has a shorter bottom than the original from Kensei, this way it fits the portafilter of the best espresso machine ever invented, the Gaggia Classic! I have also added a stand to rest the unit.

Printed nice in PLA, no brims, with a 0.6 nozzle, 0.2 layer height, 15% gyroid infill.

Modified BoM

4x M3x12 screws 1x M3 nut and a longer M3 screw (just to press fit the bearings) 8x MR63ZZ ball bearings (those are 6 mm in OD, 3 mm ID and 2.5 mm height) 2x 6813 type ball bearings (those are 85 mm OD, 65 mm ID and 10 mm height) 10x acupuncture needles

Needles fit just fine, I fixed them with a tiny drop of regular white glue so that I can remove them if I need to.
