Lulzbot toolhead latch

thingiverse

This is a compact print-in-place (PIP) latch I designed to secure my extra Lulzbot toolheads within my enclosure for my Taz5. The design can likely be used in numerous other applications. I've included the .step files if you want to modify them. I just printed several additional X Carriage Guides from Lulzbot's Dev site here and mounted them on the wall. http://devel.lulzbot.com/TAZ/nutmeg/production_parts/printed_parts/x_carriage_guide/ Print Settings Printer Brand: LulzBot Printer: TAZ 5 Rafts: No Supports: Yes Resolution: .2 Infill: 80% Notes: I used Simplify 3D for slicing and manually placed supports under the extended arm only. The small gap that didn't have support bridged very well when I printed so ymmv. The layer height is somewhat arbitrary. I suspect it would print just fine anywhere between .2 and .35 layer height. How I Designed This I designed in Fusion360. I had always wanted to try a print in place design and took the inspiration from the great Maker Faire Robot head rotation by LeFabShop that you can make out in the picture below. It's a rather simple hourglass shape with a .8mm clearance gap at the base and graduating down to a .5mm gap at the top to help a little with any first layer overage, ensuring a smooth print.
