Having printed and installed the parts from Athlon to get both the E3d Revo Micro and Sherpa Mini direct drive installed on my Mini, I found 2 problems:
1: The sherpa filament entry point was loose on capricorn bowden tube (was fine with prusa stock tube)
2: The old Prusa extruder print had a difficult-to-feed part where the filament was without tubing to support it going through the block.
Model Solutions:
1: I used the Mini Dragon Sherpa cable tidy part as measurement inspiration to create a PC4-M10 compatible passthru tube holder. This also directly uses another model incorporated into the design.
2: I took the original Prusa R4 part and remixed it to have a passthru bowden tube slot, and using another PC4-M10 adapter on the exit point to allow the entire reverse bowden tube to be anchored at both ends via the pnuematic fittings.
How to Install
1: this is mounted on the Sherpa using 2x 25mm M3 bolts and nuts
2: This directly replaces the existing R4 block, using all the same fittings as previously.
