Prusa Mk2/Mk3 Bracket for Meanwell LRS350 using AdamTech Inlet

I didn't have the original Delta PSU components to use and I try not to open power supplies, so a replacemnt 5USD AdamTech inlet is a economical choice.  Note that the original model is marked Mk3, but I'm pretty sure it is derived from the Mk2 PSU holder - so I have marked this as Mk2 and Mk3.

You will need the flat spacer part from the original model, I didn't include it here.

Problems

I'm not sure if the Mk3, Mk3S, and Mk3S+ all mount the PSU the same way. On the Mk3S+ that I modified, which had a Delta PSU, the t-nuts faced the side of the printer. This model is designed to attach on top of the extrusion, so I rotated the extrusion instead of trying to get the t-nuts out.  A worthy remix would be to change the tab on this model so this isn't necessary.

Upon installation, I found that the tab can't be attached to both t-nuts because it is too close to the end of the extrusion. Makes remixing again even more essential. I need to move on so am going to go with just one bolt, as pictured.

Print Settings

Will tolerate larger nozzles and faster speeds. I printed with a 0.6mm nozzle and 0.4mm layer heights. At least 3 perimeters. Supports recommended top support the new large opening - even ABS can print that bridge unsupported but a neater edge would be better because it locks in the inlet. I painted on the supports to position them.

Printing at 100.5% highly recommended if printing in something that shrinks such as ASA/ABS.

Installation

Be sure that both the top and bottom of the inlet lock in. Best to make sure the top and bottom edges of the opening are clean and sharp BEFORE putting in the inlet. If the inlet only half locks in, it can be hard to get back out.

Remix Info

Removed the original inlet holes. Cut the new hole. Cleaned up some of the bottom plate which had weird artifacts.
