I printed at 0.2mm in Bambu PETG with 15% gyroid infill, 3 wall thickness, 4 bottom, 4 top.
Printed on Bambu P2S
The author remixed this model.
I remodeled the dovetail Male part for mounting the caddy. It hooks over the whole top of the XBloom Studio. I also made a couple of holed in the dovetail part for a screw, I drilled a 3.5mm hole through the top of the caddy part using the 6mm (larger) hole for a guide, and used an M4 screw to sit inside the hole as a locking pin to stop the dovetail part sliding off. I guess you could also use glue.
I also slightly widened the dovetail part to be closer to a friction fit as my prints in PETG and ASA both shrunk too much to hold the caddy.
