PrintrBot Simple anchor brackets / Control Panel with or without 5mm holes for 5mm LEDs or toggle switches! I noticed from across the room that my Printrbot simple (with volume tower upgrade) had a lot of swaying motion when it was printing. I made this anchor plate to mount it to a 12" wide piece of plywood along with a custom modded ATX style power supply Immediately I noticed my prints were coming out smoother with almost no visible layer lines! Anchoring the printer greatly improved my prints! There are 2 Anchors here. One that has the 5mm holes for 5mm leds and toggle switch and one that only has the screw anchor holes (first version also has screw holes). Either can be used in the front and I do believe you could use one in the rear as well if you do not have the tower upgrade (I haven't tried it). For the tower upgrade, I just drilled 2 holes (in front and behind) each rear leg. Then just toss a zip tie through the holes and over the leg and tighten down to secure the rear legs on the Printrbot volume upgrade tower's legs) To mount the front anchor plate, I first turned the anchor upside down on my 12" x 1/4" thick board, right in front of the printrbot simple and marked where I wanted the holes for the anchor. Then drilled them to fir the 4-40x1 1/4" screws. I placed the screw heads underneath the board and tightened the nuts from the top of the anchor plate. This allows me to easily secure them with "blue" screw adhesive or adjust the tension without moving the printer. My anchor board sits on top of an equal size of neoprene to even out the screw heads and zip-ties on the bottom and protect the under-lying surface. (could use felt or foam as well.) PrintrBot Simple Front Anchor with 5mm holes for mounting 5mm LEDs and LEDs You will need a plywood board to anchor your printrbot simple to. 2x 4-40x 1 1/4" machine screws for each plate you decide to use and custom electronic parts to be installed. 1 or 2 printed plates (Installing custom electronics is beyond the scope of this document.) Simply print the which one you need (or both for front and back installation). Place it on top of the printrbot's lowest baseboard in the front, making sure it slightly overlaps the base board. mark the 2 screw holes. Then drill the holes for the screws you have chosen.1 1/4" screw are perfect for this. Insert the screws from below, with the threads pointing up. Place the anchor on top of the screws and the lip slightly over the printerbot's baseboard. Put the nuts on and tighten down until the printrbot is secure. Do the same for the rear if you do not have the tower legs (standard Simple).. If you do have the Tower upgrade. drill 2 holes in the anchor board right in front of the legs and behind each leg (4 holes total). Starting from above, thread your zip-ties through both holes and secure it from above. Tighten it down and cut off any extra length. (refer to photos of my assembly if you are unsure of any step) Place Felt, Foam, neoprene or even rubber feet under the board flat against the surface you run it on (not needed if you place it on carpet!) This will prevent the screw heads or zip-ties from making it an uneven surface . Before running your printer with the anchors installed move the x, y and z axis's to their full extent BY HAND. Make sure there is no unforseen obstruction that could damage your printer. Make sure all the parts move freely and will operate as intended! (no power supply behind the x-axis that it will hit?) if you are installing custom electronics, test the circuits completely before plugging any non-stock power to the printer! That's it! your printer is mounted (with new electronics?) and ready to go!
