VKB NXT THQ KG12 Throttle Large with Rest

prusaprinters

This is hopefully my last variation on this design. Decided I wanted a hand rest, and happened to be mucking about with a Duke Nukem 3D maker coin. The result is this variation.You need to print the centre piece in either PETG or ABS. PLA does not have strong enough layer adhesion; it will split. The centre piece needs to have the slots for the throttle axis levers scraped out on the surface that is bridged during printing. It should be a tight fit, not a press fit. Print with 50% infill. Can be printed at 0.3mm layers, though 0.2 will probably give you less post processing. I have provided 3 variations here, one with “self tapping” holes with and without the end cap holes, and one that is designed for M3 heat set inserts. My preference is the heat set inserts, though my functional in use one is just threaded straight into plastic.You need to print 2 grip panels, one for either side. These can be whatever you want. I used a silk copper PLA; I tried in TPU, and honestly it was not worth it. Print with 25% ~ 50% infill. 0.2mm layers, or finer.Lastly you need to print the hand rest, and the end cap. These can also be printed in PLA, or whatever material you wish. I used TPU for these, and it is much more comfortable then PLA or other rigid materials. Print at 0.2mm layers, with 50% infill.Lastly, you will need 11 M3x6mm screws, cap, or round head will work, to assemble it. Use the metal throttle arms, and assemble it fully off the THQ. The last step should be installing it on the THQ. Be sure to place the slot cutouts to the inside for the captive square nuts.
