QuickJack 5000 series wheel brackets

DISCLAIMER: Attaching any accessory or modification to a jack or garage lift must not alter or inhibit in any way the originally designed operation of the jack or lift. Upon every use, please verify that these casters do not prevent your jack base from making solid contact with the ground.

Description: Caster wheels for easy positioning of your jack. The casters should easily roll across your average dirty garage floor. When collapsed, they will lift your jack frame off the ground by 5/8". When properly installed, they should raise out of the way before your quickjack makes contact with your car. Tested on a stock Miata, so if it clears that car, it should easily clear under yours.

This model was remixed from the 7000TL wheel brackets. I resized it to fit the 5000 series frame. Please give the original author some love. https://makerworld.com/en/models/686887-quickjack-7000tl-wheel-brackets?replyId=2697471&replyType=4#profileId-615590

Print Settings: Wall thickness: 2.4mm, Top/bottom thickness: 1.2-1.5mm; Layer height: 50% of nozzle diameter; Infill: 30 or 35% cubic subdivision; Filament: PETG. Expect ~300-310 g per model.

Recommended: 0.6mm nozzle; 0.3mm layer height; 4 wall layers; 5 top/bottom layers.

Acceptable: 0.4mm nozzle; 0.2mm layer height; 6 wall layers; 6 top/bottom layers.

I have found that printing in the orientation as downloaded works best. I place support blockers over the four caster bolt-holes only. I have found normal support with conical base is slightly better than tree, but both would work.

Hardware (quantity in parantheses):

(2500g) PETG filament, your choice of color.

(4) 3/8" x 16.25" threaded rod. (I found purchasing two 3-foot rods and cutting them to length was the most economical.)

(8) 3/8" nylon lock nuts (I have found it beneficial to have one extra - see install tips)

(8) 3/8" fender washer, 1" OD

(8) Harbor Freight 1-5/8" wheel casters (any caster with a mounting plate size of 2" x 1.25", but these will give you the best height.)

(32) M6 x 30mm Hex bolts

(32) M6 hex nuts

(8) 16" zip ties. (I used [16] 8" zip ties, it was on the same aisle as the wheel casters at Harbor Freight.)

Tools:

(2) 9/16" socket wrenches

(1) 10mm socket wrench

(1) {optional, recommended} 3/8" metal drill bit (plus small diameter bit for making pilot hole).

(1) rubber mallet

(1) trim knife OR wire cutters (for trimming zip ties)

Install Tips:

-Cut threaded rods to size first.

-Depending on print settings, the channel for the 3/8 rod might be slightly undersized. Prior to install, test fit the rod to each printed part. Use a rubber mallet to gently tap it in until it can move back and forth with minor resistance.

-It is recommended to drill two 3/8" holes into the jack's front label plate, to allow pass-through of the front zip-ties. [Some people prefer to instead zip tie the front wheel blocks to each other, thus not requiring drilling. This is acceptable.] {HINT: Turn your jack upside down for drilling, it makes it easier to prevent accidents. DO NOT drill into the box-tube frame, as that is a good way to ruin a very expensive jack.}

-I have found the best order of install to be thus:

A) Place your tall spacer blocks under the jack so that your jack is off the ground.

B) Install caster wheels onto each printed part.

C) Insert threaded rod into left wheel assembly, insert left wheel and rod into jack. Guide rod into right wheel assembly and tap into place.

D) Secure zip ties and tighten.

E) Add washers and lock nuts and tighten until the wheel assemblies are flush.

F) If you find that one nut is tightening and the other is not, I have found that stacking an extra nut on excess thread allows the tightening of the opposite side.

G) Verify snugness of zip ties and trim.
