This is a learning process of time, technique, and calibration … it's also a commitment of filament. I'm printing several of these now, so I'd love your feedback if you go for it, or wait a little bit and I can share what more I learn.
Step 1 - Print the support ring.
I prefer to print with zero top and bottom layers and tight enough infill to provide a good support structure but to allow air to keep moving to avoid thermal deformation. I also printed in PLA+ which has worked well for this technique several times over. PETG might be a better choice but I haven't tried it yet.
Think of the support ring as a single use, but it is possible to get more than one use if you handle it carefully.
Step 2 - Load and slice the foot pad ring. Insert a print pause just before the top lip starts.
With 0.28mm layers, my pause is at layer 32 with a height of 8.88mm. I found an 8% gyroid infill to have nice cushion but poor strength. 20% gyroid is probably 3-4% too much for what I want. But it stronger - also needed a lot of force to install.
Step 3 - Print the foot pad ring.
At the pause, insert the preprinted support. Then continue the print.
Step 4 - Remove the support ring.
This may be easier with the quarter supports as it takes some force. I used a thin scraper to release the TPU layer from the top side of the support.
The risk with the quarter supports is they might get moved around by the printhead.
Step 5 - Install the foot pad.
I used a screw driver similar to using a tire iron to install/remove a tire.
