Black PSU replacement brace for Prusa i3 mk3s

A stiff brace replacement for black PSU of Prusa i3 mk3s. No additional fasteners but 2 hooks connects the brace to the top side of extrusion. It can be used together with my Squash ball feet for Prusa i3 mk3s (https://www.prusaprinters.org/prints/45857-squash-ball-feet-for-prusa-i3-mk3s)

For fastening points to the frame, I used 2x ruthex threaded insert M4. (https://www.amazon.de/gp/product/B07YSV66Y5/ref=ppx_yo_dt_b_asin_title_o06_s01?ie=UTF8&th=1)

Because of its stiffness, i recommend PLA over PETG.

Update (03.04.2022)

I added a M4 hex nut version but I haven't tested it yet. The nut on the upper position needs to be slide in. If somebody is willing to test, please let me know your result.

Please note that this version needs 2x M4-14 or M4-16 screws.

Prusa i3 mk3sのPSU(黒)を移動した際に用いるブレースです。追加のねじ締結部はありませんが、ツメ形状がアルミ押出材フレームの上面に引っかかることでしっかりとサポートします。私のSquash ball feet for Prusa i3 mk3s (https://www.prusaprinters.org/prints/45857-squash-ball-feet-for-prusa-i3-mk3s)と同時使用可能です。

中央のフレームとの締結部には ruthex製のインサートナットM4を２個使っています。 (https://www.amazon.de/gp/product/B07YSV66Y5/ref=ppx_yo_dt_b_asin_title_o06_s01?ie=UTF8&th=1)

材料の剛性はPLAのがPETGより高いので、PLAをお勧めします。
