JWST Hanging Wall Model w/ 200mm Mirrors

thingiverse

THIS IS A WORK IN PROGRESS SO FILES MAY CHANGE! PROGRESS UPDATE: Took much longer to get more filament than I hoped but I just started the last print today! Never give up, never surrender! Working on the backing now. I decided to go with peg board because it's lighter, has ready-made holes for mounting, and will hopefully provide some better hold for adhesive with the holes. Benchy for scale! My goal here is to take the [excellent design by floribot](https://www.thingiverse.com/thing:5223379) and adapt it to [200mm mirrors I already purchased](https://www.amazon.com/gp/product/B07JN5M37X) for printing on an Ender3 Pro. This is a bit of a challenge because with the shield integrated into the hex outlines and scaled appropriately, the 3-shield pieces are too large for the Ender3 Pro print bed. To solve this problem I added an additional parameter to the SCAD, "shield_only" which just removes the entire hexagon leaving only the shields as separate pieces, and then printing all the hexagons with shields=0. This results in 28 prints: jwst-200mm-0-shields-hole-x18 jwst-200mm-2-shields-x6 jwst-200mm-3-shields-x6-x3 (3 prints with 2 pieces each for 6 total pieces) jwst-200mm-0-shields-center-x1 Filament: 24.29 x 18 = 437.22 34.13 x 6 = 204.78 42.62 x 3 = 127.86 64.34 x 1 = 834.2g Time: 2h14m x 18 = 2412m 2h56m x 6 = 1056m 3h42m x 3 = 666m 5h17m x 1 = 317m = 4451m = 74h11m Earlier versions of this used even more oversized values of mirror_length (202, 201) but through test prints and test fitting all the mirrors I have, I found that the 200 value works perfectly. My mirrors are slightly under size measuring ~198.5mm from point to point and that ~1.5mm of extra space is more than enough play for a nice tight fit. I also stripped out the ironing as after some testing the result was not worth the added time and added some brims to the shielding pieces due to the size and sharp points which don't like to stay on the print bed.
