20mm MFT style bench caps only 1gram of filament

These are super efficient bench caps for 20mm MFT style work benches with a 45 degree chamfer. I couldn't find anything that didn't seem over engineered so I designed my own from scratch. They each use only 1 gram of PETG and aside from calibration take about one minute a piece to print on my P1S. An optional M5 washer snaps into the underside for easy removal with a magnet, no glue required. The washer should have an OD of 10mm and a height of 1mm, like these https://www.amazon.com/dp/B0DPZB86J8?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1  Again, these are designed to plug 20mm chamfered holes in a workbench so small objects don't fall into the holes.
