Prior to using this spool mount, I was unable to successfully print Siraya Tech Flex TPU Filament - 85A due to the filament being limp and elastic. I likened it to trying to push a wet noodle through a straw. This setup works well as shown in the clip.
Fabrication:
Print the Centari_Carbon_Overhead_Spool_Arm, I used PETG-CF, 2 wall loops, 25% Gyroid infill, no brim. I printed it oriented with the spool mount hole up and I did not require any supports.
Print the Centari_Carbon_Spool_Arm_Retainer, oriented as shown. As before, I used PETG-CF, 2 wall loops, 25% Gyroid infill, no brim.
The retainer clip helps stabilize the arm when mounted to the printer, I used an M4 heat-set insert and a 25mm long M4 socket head cap screw. I added RemiRafael's (@RemiRafael) excellent knurled knob for the M4 screw. It allows for additional tightening with a hex driver.
Mounting:
To mount, place the spool arm on the printer as shown:
Align the retainer clip alongside the arm as shown:
Insert the M4 screw and tighten to stabilize arm:
Prepare for use by disconnecting the PFTE filament guide tube at the print head and temporarily replacing it with an ~80-120mm piece of spare PFTE tube for use with the overhead spool.
