Reinforced and Numbered MMU3 Plateholder for Loading Fork MK4

Loading the org. Prusa buffer for MMU3 is sometimes a mess. The cassette technique is great, but when you have easy access from all sides then the loading fork of @saphir is a great tool, link see below.

What I noticed is that the original plate holderhas reinforcements at the both ends, e.g. slots 1 and 5. There the fork has an excellent backup to push the fork towards the buffer wheels. Unfortunately this force is gone when using slots 2 through 4, as there is a piece of material missing. By reengineering the plate holder (quite simple part) I achieved a strong backup on all slots 1 through 5 (mind the mark-ups in the photographs).

Additionally I integrated some numbers (1-5) on the plate holder, so it is easy to identify the correct slot. To get those nicely readable I needed to make a top and a bottom part.

In the files sectionyou'll find a more simple part, in one color, no numbers, this can just substitute the bottom plate holder. But if you have an MMU, why not using the numbers?

This works fine.
